The initial public offering of Units in each Trust has been completed. The Units
offered hereby are issued and outstanding Units which have been acquired by the
Sponsor either by purchase from the Trustee of Units tendered for redemption or
in the secondary market.
 
The objectives of each Trust are the providing of interest income which, in the
opinion of counsel is, under existing law, excludable from gross income for
Federal income tax purposes (except in certain instances depending on the Unit
Holder), through investment in a fixed portfolio consisting primarily of
investment grade long-term (or intermediate term in the case of the State
Trusts) state, municipal and public authority debt obligations, and the
conservation of capital. In addition, in the opinion of bond counsel to the
issuers of the obligations, the interest income on the obligations held by the
underlying unit investment trusts composing Multistate Series 59 designated as
the California Trust (Insured Intermediate Term-Laddered Maturities) and the New
York Trust (Insured Intermediate Term-Laddered Maturities) (the 'California
Trust (Insured)' and the 'New York Trust (Insured),' collectively the 'State
Trusts,' or singularly, the 'State Trust') (the 'Trusts' or the 'Trust' or in
the case of the California Trust (Insured) and the New York Trust (Insured) the
'Insured Trusts' as the context requires), is exempt from state and any local
income taxes to individual Unit Holders resident in the State for which the
State Trust is named. Education facilities bonds constitute 80% of the aggregate
bid price of all bonds in the New York Trust (Insured). There is, of course, no
guarantee that the Trusts' objectives will be achieved. The value of the Units
of each Trust will fluctuate with the value of the portfolio of underlying
Securities. Each municipal bond in the Insured Trusts is covered by an
irrevocable insurance policy as a result of which the Units of the Insured Trust
were rated 'AAA' by Standard & Poor's Corporation as of the Date of Deposit.
Insurance guaranteeing the scheduled payment of principal of and interest on the
securities in the California Trust (Insured) and the New York Trust (Insured) to
the maturity of such Securities has been obtained at the cost of the issuer at
the time of issuance. No representation is made as to the insurers' ability to
meet their commitments. The Securities in Series 160 are not insured. The
Securities in the Trusts are not insured by The Prudential Insurance Company of
America. The Prospectus indicates the extent to which interest income of each
Trust is subject to alternative minimum tax under the Internal Revenue Code of
1986, as amended. See 'Schedule of Portfolio Securities' and 'Portfolio
Summary.' The California Trust (Insured) and the New York Trust (Insured) were
structured as of the Date of Deposit to return to Unit Holders each year
beginning in 1998, approximately 20% of the per Unit principal amount of the
Securities included in each Trust. See 'Schedule of Portfolio Securities.'
 
                            Minimum Purchase: 1 Unit
 
PUBLIC OFFERING PRICE of the Units of each Trust is equal to the aggregate bid
side evaluation of the underlying Securities in each Trust's Portfolio divided
by the number of Units outstanding in such Trust, plus a sales charge as set
forth in the table herein. (See Part B--'Public Offering of Units--Volume
Discount.') Units are offered at the Public Offering Price plus accrued
interest. (See Part B--'Public Offering of Units.')

                                    SUMMARY
 
    National Municipal Trust, Series 160 ('National Trust (Uninsured)') and
Multistate Series 59 which consists of two separate underlying unit investment
trusts designated as the California Trust (Insured Intermediate Term-Laddered
Maturities) and the New York Trust (Insured Intermediate Term-Laddered
Maturities) (the 'California Trust (Insured)' and the 'New York Trust
(Insured),' collectively, the 'State Trusts,' or singularly, the 'State Trust')
(the 'Trusts' or the 'Trust' or in the case of the California Trust (Insured)
and the New York Trust (Insured) the 'Insured Trusts' as the context requires)
are composed of interest-bearing municipal bonds (the 'Securities'). The
Securities in the State Trusts are issued primarily by or on behalf of the State
for which the State Trust is named and counties, municipalities, authorities and
political subdivisions thereof. The interest on these bonds, in the opinion of
bond counsel to the issuing governmental authorities, is, under existing law,
excludable from gross income for Federal income tax purposes (except in certain
instances depending on the Unit Holder) and, as respects the underlying State
Trusts, exempt from State and any local income taxes to individual Unit Holders
resident in the State for which the State Trust is named.
 
    INSURANCE guaranteeing the scheduled payments of principal of and interest
on the Securities in the portfolios of the Insured Trust has been obtained by
the issuer at the cost of the issuer at the time of issuance of the Securities
from AMBAC Indemnity Corporation ('AMBAC'), Capital Markets Assurance
Corporation ('CapMAC'), Connie Lee Insurance Company ('Connie Lee'), Capital
Guaranty Insurance Company ('Cap. Gty.'), Financial Security Assurance ('FSA'),
Municipal Bond Insurance Association ('MBIA'), Municipal Bond Investors
Assurance Corporation ('MBIAC'), and/or Financial Guaranty Insurance Company
('Financial Guaranty' or 'FGIC') (singularly, each an 'Insurance Company' and,
collectively, the 'Insurance Companies'). (See Part B--'The Trust--Insurance on
the Securities in the Portfolio of an Insured Trust.') As a result of the
insurance, the Securities and the Units of the Insured Trusts have received a
rating of 'AAA' by Standard & Poor's Corporation. There can be no assurance that
Units of the Insured Trusts will retain this 'AAA' rating. There is, of course,
no guarantee that the objectives of the Insured Trusts will be achieved since an
issuer may be unable to meet its principal and interest payment obligations and,
in such event, the Insurance Company involved may be unable to satisfy its
insurance obligation. Insurance is not a substitute for the basic credit of an
issuer, but supplements the issuer's existing credit and provides additional
security therefor. NO REPRESENTATION IS MADE AS TO THE ABILITY OF THE INSURANCE
COMPANIES TO MEET THEIR COMMITMENTS.
 
    MONTHLY DISTRIBUTIONS of principal, premium, if any, and interest received
by each Trust will be made on or shortly after the twenty-fifth day of each
month to Unit Holders of record as of the immediately preceding Record Date.
(See Part B--'Rights of Unit Holders--Distribution of Interest and Principal.')
In the case of the California Trust (Insured) or the New York Trust (Insured),
the Trustee will distribute, to Unit Holders of record on the date four business
days prior to the maturity date of a Security, the principal relating to such
matured Security on the business day next following such maturity date.
Alternatively, Unit Holders may elect to have their distributions reinvested in
the Reinvestment Program of the Sponsor, as, if and when such program is
available to Unit Holders. (See Part B--'Reinvestment Program.')
 
    LADDERED MATURITIES. The California Trust (Insured) and the New York
(Insured) will return to Unit Holders each year beginning in 1998 approximately
20% of the per Unit principal amount of the Securities included in each Trust.
(See 'Schedule of Portfolio Securities.') If interest rates rise, Unit Holders
may be able to reinvest their principal distributions as received in
higher-yielding obligations. Conversely, however, if interest rates decline,
Unit Holders will be receiving payments of principal at times when only
lower-yielding investments of comparable quality are available. Reinvesting at
such time may result in an over-all lower yield than would result from a single
investment
                                      A-i
 
<PAGE>
maturing at the close of the life of the Trust. Such return of 20% of principal
each year may not be achieved due to various factors including the sale of bonds
by the Trust to meet redemptions of Units or for other permitted reasons, and
the bankruptcy of an issuer where the insurance company insuring the bond does
not make the scheduled principal payment.
 
    THE SPONSOR, although not obligated to do so, presently intends to maintain
a secondary market for the Units in each Trust based on the aggregate bid side
evaluation of the underlying Securities, as more fully described under Part
B--'Public Offering of Units--Secondary Market--Public Offering Price.' If such
a market is not maintained, a Unit Holder may be able to dispose of his Units
only through redemption at prices based on the aggregate bid side evaluation of
the underlying Securities. (See Part B--'Rights of Unit
Holders--Redemption--Computation of Redemption Price per Unit.')
 
    SPECIAL CONSIDERATIONS. An investment in Units of each Trust should be made
with an understanding of the risks which an investment in fixed rate long-term
(or intermediate term) debt obligations may entail, including the risk that the
value of the Units will decline with increases in interest rates. Insurance
obtained by the Security issuer does not guarantee the market value of the
securities or the value of the Units. Any such insurance obtained by the issuer
may be considered to represent an element of market value in regard to the
Securities thus insured. The insurance on the Securities in the Insured Trusts
does not protect Unit Holders from the risk that the value of the units may
decline. (See Part B--'The Trust--Portfolio Summary.') The ratings of the
Securities set forth in Part A--'Schedule of Portfolio Securities' may have
declined due to, among other factors (including a decline in the
creditworthiness of an insurer in the case of an insured trust which may also
result in a decline in the 'AAA' rating of the units of an insured trust), a
decline in creditworthiness of the issuer of said Securities.

Portfolio Summary
 
   National Trust (Uninsured)
 
    The Portfolio contains 10 issues of Securities of issuers located in 6
states. One of the issues (1.6%* of the Trust) is a general obligation of a
governmental entity and is backed by the general taxing powers of that entity.
The remaining issues are payable from the income of specific projects or
authorities and are not supported by the issuer's power to levy taxes. Although
income to pay such Securities may be derived from more than one source, the
primary sources of such income and the percentage of issues deriving income from
such sources are as follows: airport facilities: 13.2%* of the Trust; health and
hospital facilities: 33.1%* of the Trust; housing facilities: 12.9%* of the
Trust; lease facilities: 13.6%* of the Trust; utility facilities: 12.9%* of the
Trust; tax allocation bonds: 12.7%* of the Trust. The Trust is concentrated in
health and hospital facilities Securities.
 
- ------------
    * Percentages computed on the basis of the aggregate bid price of the
Securities in the Trust on July 23, 1997.
 
                                      A-ii
 
<PAGE>
    The Portfolio also contains Securities representing 12.9%* of the Trust
(single-family housing securities) which are subject to the requirements of
Section 103A of the Internal Revenue Code of 1954, as amended, or Section 143 of
the Internal Revenue Code of 1986.
 
    60.6%* of the Securities in the Trust are rated by Standard & Poor's
Corporation (14.5%* being rated AAA, 12.9%* being rated AA, 26.3%* being rated A
and 6.9%* being rated BBB) and 39.4%* of the Securities in the Trust are rated
Baa by Moody's Investors Service. For a description of the meaning of the
applicable rating symbols as published by Standard & Poor's and Moody's, see
Part B--'Bond Ratings.' It should be emphasized, however, that the ratings of
Standard & Poor's and Moody's represent their opinions as to the quality of the
securities which they undertake to rate and that these ratings are general and
are not absolute standards of quality.
 
    Nine Securities in the Trust have been issued with an 'original issue
discount.' (See Part B--'Tax Status.')
 
    Of these original issue discount bonds, approximately 6.3% of the aggregate
principal amount of the Securities in the Trust (although only 1.6%* of the
aggregate bid price of all Securities in the Trust) are zero coupon bonds
(including bonds known as multiplier bonds, money multiplier bonds, capital
appreciation bonds, capital accumulator bonds, compound interest bonds, and
discount maturity payment bonds).
 
   Alternative Minimum Tax
 
    As of the date of the Summary of Essential Information, the Sponsor's
affiliate, The Prudential Investment Corporation, estimates that 26.0% of the
estimated annual income per Unit consists of interest on private activity bonds,
which interest is to be treated as a tax preference item for alternative minimum
tax purposes (See 'Tax Status' and 'Schedule of Portfolio Securities').
 
    The Sponsor participated as sole underwriter or manager or member of
underwriting syndicates from which approximately 39.2%* of the Trust was
acquired.
 
   California Trust (Insured)
 
    The Portfolio contains 5 issues of Securities of issuers located in the
State of California. All of the issues are payable from the income of specific
projects or authorities and are not supported by the issuer's power to levy
taxes. Although income to pay such Securities may be derived from more than one
source, the primary sources of such income and the percentage of issues deriving
income from such sources are as follows: lease facilities: 40.2%* of the Trust;
special tax bonds: 20.2%* of the Trust; tax allocation bonds: 39.6%* of the
Trust. The Trust is concentrated in lease facilities and tax allocation bonds.
 
    100%* of the Securities in the Trust are rated AAA by Standard & Poor's
Corporation. For a description of the meaning of the applicable rating symbols
as published by Standard & Poor's see Part B--'Bond Ratings.' It should be
emphasized, however, that the ratings of Standard & Poor's represent its opinion
as to the quality of the Securities which it undertakes to rate and that these
ratings are general and are not absolute standards of quality.
 
    Four Securities in the Trust have been issued with an 'original issue
discount.' (See Part B--'Tax Status.')
 
    The Securities in the Trust are insured to maturity by the insurance
obtained by the issuer from the following insurance companies: AMBAC: 40.2%*;
FSA: 20.2%*; FGIC: 39.6%*.
 
   New York Trust (Insured)
 
    The Portfolio contains 5 issues of Securities of issuers located in the
State of New York. All of the issues are payable from the income of specific
projects or authorities and are not supported by the issuer's power to levy
taxes. Although income to pay such Securities may be derived from more than one
source, the primary sources of such income and the percentage of issues deriving
income from such sources are as follows: education facilities: 80.6%* of the
Trust; health and hospital facilities: 19.4%* of the Trust. The Trust is
concentrated in education facilities Securities.
 
    100%* of the Securities in the Trust are rated AAA by Standard & Poor's
Corporation. For a description of the meaning of the applicable rating symbols
as published by Standard & Poor's, see Part B--'Bond Ratings.' It should be

    (1) The Date of Deposit is the date on which the Indenture was signed and
the deposit of Securities with the Trustee was made.
    (2) This Public Offering Price is computed as of July 23, 1997 and may vary
from the Public Offering Price on the date of this Prospectus or any subsequent
date.
    (3) Includes Trustee's fee, Sponsor's Portfolio supervision fee, estimated
expenses and Evaluator's fees.
    (4) Exclusive of accrued interest which to July 28,1997, the expected date
of settlement for the purchase of Units on July 23, 1997 was $17.06.
    (5) The estimated current return is increased for transactions entitled to a
reduced sales charge. (See Part B--'The Trust'--'Estimated Annual Income and
Current Return per Unit.')
    (6) The Estimated Current Return is calculated by dividing the Estimated Net
Annual Income per Unit by the Public Offering Price per Unit. The Estimated Net
Annual Income per Unit will vary with changes in fees and expenses of the
Trustee and the Evaluator and with the principal prepayment, redemption,
maturity, exchange or sale of Securities while the Public Offering Price will
vary with changes in the bid price of the underlying Securities; therefore,
there is no assurance that the present Estimated Current Return indicated above
will be realized in the future. The Estimated Long-Term Return is calculated on
a pre-tax basis using a formula which takes into consideration, and factors in
the relative weightings of, the market values, yields (which takes into account
the amortization of premiums and the accretion of discounts) and estimated
retirements of all of the Securities in the Trust and takes into account the
expenses and sales charge associated with each Unit. Since the market values and
estimated retirements of the Securities and the expenses of the Trust will
change, there is no assurance that the present Estimated Long-Term Return as
indicated above will be realized in the future. The after-tax Estimated
Long-Term Return will be lower to the extent of any taxation on the disposition
of Securities. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of the Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the Estimated
Current Return calculations include only Net Annual Interest Income and Public
Offering Price as of the above indicated calculation date of the Summary of
Essential Information.

of Securities. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of the Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the Estimated
Current Return calculations include only Net Annual Interest Income and Public
Offering Price as of the above indicated calculation date of the Summary of
Essential Information.

Risk Factors
 
    Potential purchasers of the Units of a State Trust should consider the fact
that the Trust's Portfolio consists primarily of Securities issued by the state
for which such State Trust is named or its municipalities or authorities and
realize the substantial risks associated with an investment in such Securities.
Each State Trust is subject to certain additional risk factors:
 
    The Sponsor believes the information summarized below describes some of the
more significant aspects of each of the State Trusts. The sources of such
information are the official statements of issuers as well as other publicly
available documents. While the Sponsor has not independently verified this
information, it has no reason to believe that such information is not correct in
all material respects.
 
California Trust
 
    Since the start of the 1990-91 fiscal year, California (the 'State') has
faced the worst economic, fiscal and budget conditions since the 1930s.
Construction, manufacturing (especially aerospace), exports and financial
services, among others, have all been severely affected. Job losses have been
the worst of any post-war recession and have been estimated to exceed 800,000.
While the most severe point of the recession has been estimated to have occurred
in late 1993, pre-recession job levels are not expected to be reached for
several more years.
 
    The recession has affected State tax revenues, which mirror economic
conditions. It has also caused increased expenditures for health and welfare
programs. The State has also been facing a structural imbalance in its budget
with the largest programs supported by the General Fund (K-12 schools and
community colleges, health, welfare and corrections) growing at rates higher
than the growth rates for the principal revenue sources of the General Fund.
(The General Fund, the State's main operating fund, consists of revenues which
are not required to be credited to any other fund.) As a result, the State has
experienced recurring budget deficits.
 
    Employment, income, and retail sales in the State have shown modest
increases over the past two years, indicating some recovery from recessionary
conditions. These increases notwithstanding, pre-recession job levels are not
expected to be reached until 1997.
 
    Together with the federal government, which is providing over $9.5 billion
in aid, the State is committed to assisting local governments, individuals and
businesses suffering damage caused by the Northridge earthquake, as well as to
assisting in the repair and replacement of State-owned facilities.
 
    On December 6, 1994, Orange County, California (the 'County'), together with
its pooled investment funds (the 'Pools'), filed for protection under Chapter 9
of the federal Bankruptcy Code.
 
    On May 2, 1995, the Bankruptcy Court approved a settlement agreement
covering claims of the other participating entities against the County and the
Pools. Most participants have received in cash 80% (90% for school districts) of
their Pools' investments with the balance to be paid in the future.
 
    The State bears no existing obligation in connection with any of the
outstanding obligations or securities of the County or any of the other
participating entities. It may, however, be necessary for the State to intervene
if the County lacks sufficient resources to maintain County administered State
programs. In this regard, the State cannot predict what, if any, action may
occur. The Legislature is considering the County's new financial plan and other
proposals relating to the County bankruptcy, including possible State oversight
of County finances. None of the proposals, however, presently involve any direct
State financial support of the County.
 
   1995-96 Budget
 
    The State began the 1995-96 fiscal year with strengthening revenues based on
an improving economy and the smallest nominal 'budget gap' to be closed in many
years.
 
    The 1995-96 Budget Act, signed by the Governor on August 3, 1995, projects
General Fund revenues and transfers of $44.1 billion, about $2.2 billion higher
than projected revenues in 1994-95. The Budget Act projects Special Fund
revenues of $12.7 billion, an increase from $12.1 billion projected in 1994-95.
 
    The 1995-96 Budget Act projects General Fund expenditures and transfers of
$43.4 billion, an increase of $168 million over 1994-95. The Budget Act also
projects Special Fund expenditures of $13.4 billion, a decrease of $700 million
from 1994-95 projected expenditures. The principal features of the Budget Act
were the following:
                                     A-viii
 
<PAGE>
    1. Proposition 98 funding for schools and community colleges will increase
by about $1 billion (General Fund) and $1.2 billion total above revised 1994-95
levels. Because of higher than projected revenues in 1994-95, an additional $543
million is appropriated to the 1994-95 Proposition 98 entitlement. A significant
component of this amount is a block grant of about $54 per pupil for any
one-time purpose. Per-pupil expenditures are projected to increase by another
$126 in 1995-96 to $4,435. A full 2.7% cost of living allowance is funded for
the first time in several years. The budget compromise anticipates a settlement
of the CTA v. Gould litigation.
 
    2. Cuts in health and welfare costs totaling about $900 million, some of
which would require federal legislative approval.
 
    3. A 3.5% increase in funding for the University of California ($90 million
General Fund) and the California State University system ($24 million General
Fund).
 
    4. The Budget assumes receipt of $473 million in new federal aid for costs
of illegal immigrants, in excess of federal government commitments. This amount
is considerably less than the summer 1994 two-year budget proposal estimate, and
is somewhat lower than the estimate in the January 1995 Governor's Budget.
 
    5. General Fund support for the Department of Corrections is increased by
about 8 percent over 1994-95, reflecting estimates of increased prison
population. This amount is less than was proposed in the Governor's Budget.
 
    THE FOREGOING DISCUSSION OF THE 1995-96 FISCAL YEAR BUDGET IS BASED IN LARGE
PART ON STATEMENTS MADE IN A RECENT 'PRELIMINARY OFFICIAL STATEMENT' DISTRIBUTED
BY THE STATE OF CALIFORNIA. IN THAT DOCUMENT, THE STATE INDICATED THAT ITS
DISCUSSION OF THE FISCAL YEAR BUDGET IS BASED ON ESTIMATES AND PROJECTIONS OF
REVENUES AND EXPENDITURES FOR THE CURRENT FISCAL YEAR AND MUST NOT BE CONSTRUED
AS STATEMENTS OF FACT. THE STATE NOTED FURTHER THAT THE ESTIMATES AND
PROJECTIONS ARE BASED UPON VARIOUS ASSUMPTIONS WHICH MAY BE AFFECTED BY NUMEROUS
FACTORS, INCLUDING FUTURE ECONOMIC CONDITIONS IN THE STATE AND THE NATION, AND
THAT THERE CAN BE NO ASSURANCE THAT THE ESTIMATES WILL BE ACHIEVED.
 
   State Appropriations Limit
 
    The State is subject to an annual appropriations limit imposed by Article
XIIIB of the State Constitution (the 'Appropriations Limit'), and is prohibited
from spending 'appropriations subject to limitation' in excess of the
Appropriations Limit. Article XIIIB, originally adopted in 1979, was modified
substantially by Propositions 98 and 111 in 1988 and 1990, respectively.
'Appropriations subject to limitation' are authorizations to spend 'proceeds of
taxes,' which consist of tax revenues and certain other funds, including
proceeds from regulatory licenses, user charges or other fees to the extent that
such proceeds exceed the reasonable cost of providing the regulation, product or
service. The Appropriations Limit is based on the limit for the prior year,
adjusted annually for certain changes, and is tested over consecutive two-year
periods. Any excess of the aggregate proceeds of taxes received over such
two-year period above the combined Appropriation Limits for those two years is
divided equally between transfers to K-14 districts and refunds to taxpayers.
 
    Exempted from the Appropriations Limit are debt service costs of certain
bonds, court or federally mandated costs, and, pursuant to Proposition 111,
qualified capital outlay projects and appropriations or revenues derived from
any increase in gasoline taxes and motor vehicle weight fees above January 1,
1990 levels. Some recent initiatives were structured to create new tax revenues
dedicated to specific uses and expressly exempted from the Article XIIIB limits.
The Appropriations Limit may also be exceeded in cases of emergency arising from
civil disturbance or natural disaster declared by the Governor and approved by
two-thirds of the Legislature. If not so declared and approved, the
Appropriations Limit for the next three years must be reduced by the amount of
the excess.
 
    Because of the complexities of Article XIIIB, the ambiguities and possible
inconsistencies in its terms, the applicability of its exceptions and exemptions
and the impossibility of predicting future appropriations, the Sponsor cannot
predict the impact of this or related legislation on the bonds in the Insured
California Trust Portfolio. Other Constitutional amendments affecting state and
local taxes and appropriations have been proposed from time to time. If any such
initiatives are adopted, the State could be pressured to provide additional
financial assistance to local governments or appropriate revenues as mandated by
such initiatives. Propositions such as Proposition 98 and others that may be
adopted in the future, may place increasing pressure on the State's budget over
future years, potentially reducing resources
 
                                      A-ix
 
<PAGE>
available for other State programs, especially to the extent that the Article
XIIIB spending limit would restrain the State's ability to fund such other
programs by raising taxes.
 
   State Indebtedness
 
    As of August 1, 1995, the State had over $18.93 billion aggregate amount of
its general obligation bonds outstanding. General obligation bond authorizations
in an aggregate amount of approximately $2.81 billion remained unissued as of
August 1, 1995. The State also builds and acquires capital facilities through
the use of lease purchase borrowing. As of August 1, 1995, the State had
approximately $5.56 billion of outstanding Lease-Purchase Debt.
 
    In addition to the general obligation bonds, State agencies and authorities
had approximately $18.98 billion aggregate principal amount of revenue bonds and
notes outstanding as of June 30, 1995. Revenue bonds represent both obligations
payable from State revenue-producing enterprises and projects, which are not
payable from the General Fund, and conduit obligations payable only from
revenues paid by private users of facilities financed by such revenue bonds.
Such enterprises and projects include transportation projects, various public
works and exposition projects, educational facilities (including the California
State University and University of California systems), housing, health
facilities and pollution control facilities.
 
   Litigation
 
    The State is a party to numerous legal proceedings, many of which normally
occur in governmental operations. In addition, the State is involved in certain
other legal proceedings that, if decided against the State, might require the
State to make significant future expenditures or impair future revenue sources.
 
   Ratings
 
    On July 15, 1994, Standard & Poor's Corporation ('Standard & Poor's'),
Moody's Investors Service, Inc. ('Moody's'), and Fitch Investors Service, Inc.
('Fitch') all downgraded their ratings of California's general obligation bonds.
These bonds are usually sold in 20- to 30-year increments and used to finance
the construction of schools, prisons, water systems and other projects. The
ratings were reduced by Standard & Poor's from 'A+' to 'A,' by Moody's from 'Aa'
to 'A1,' and by Fitch from 'AA' to 'A.' Since 1991, when it had a 'AAA' rating,
the State's rating has been downgraded three times by all three ratings
agencies. All three agencies cite the 1994-95 Budget Act's dependence on a
'questionable' federal bailout to pay for the cost of illegal immigrants, the
Proposition 98 guaranty of a minimum portion of State revenues for kindergarten
through community college, and the persistent deficit requiring more borrowing
as reasons for the reduced rating. Another concern was the State's reliance on a
standby mechanism which could trigger across-the-board reductions in all State
programs, and which could disrupt State operations, particularly in fiscal year
1995-96. However, a Standard & Poor's spokesman stated that, although the
lowered-ratings means California is a riskier borrower, Standard & Poor's
anticipates that the State will pay off its debts and not default. There can be
no assurance that such ratings will continue for any given period of time or
that they will not in the future be further revised.
 
    Fitch upgraded its rating of California's general obligation bonds from 'A'
to 'A+' on February 26, 1996. No rating change was made, however, by either
Moody's or Standard & Poor's as of that date.
 
    As a result of Orange County's Chapter 9 bankruptcy filing on December 6,
1994, Moody's suspended the county's bond ratings until January 6, 1995, when it
reinstated them at a rating of 'Caa.' On December 6, 1994, Standard & Poor's cut
its rating of all Orange County debt from 'AA-' to 'CCC,' a level below
investment grade and an indication of high risk and uncertainty, and on December
8, 1994, Standard & Poor's further reduced its rating to 'D' indicating default
status. Fitch does not rate Orange County bonds. It is anticipated that as
Orange County's credit and bond ratings fall, it will have difficulty in getting
loans or selling its bonds to raise money. Additionally, the County's bankruptcy
filing could affect about 180 municipalities, school districts, and other
municipal entities which entrusted billions of dollars to Orange County to
invest. Standard & Poor's has informed such entities that they have been placed
on negative credit watch, the usual step prior to a downgrade of credit rating.
 
    The Sponsor believes the information summarized above describes some of the
more significant aspects relating to the Insured California Trust. The sources
of such information are Preliminary Official Statements and Official Statements
relating to the State's general obligation bonds and the State's revenue
anticipation notes, or obligations of other issuers located in the State of
California, or other publicly available documents. Although the Sponsor has not
independently verified this information, it has no reason to believe that such
information is not correct in all material respects.

New York Trust
 
   New York State
 
    The 1996-97 Executive Budget proposes $3.9 billion in actions to balance the
1996-97 Financial Plan. Before reflecting any actions proposed by the Governor
to restrain spending, General Fund disbursements for 1996-97 were projected at
$35 billion, an increase of $2.3 billion or 7 percent from 1995-96. This
increase would have resulted from growth in Medicaid, inflationary increases in
school aid, higher fixed costs such as pensions and debt service, collective
bargaining agreements, inflation, and the loss of non-recurring resources that
offset spending in 1995-96. Receipts would have been expected to fall by $1.6
billion. This reduction would have been attributable to modest growth in the
State's economy and underlying tax base, the loss of non-recurring revenues
available in 1995-96 and implementation of previously enacted tax reduction
programs.
 
    In recent years, State actions affecting the level of receipts and
disbursements, as well as the relative strength of the State and regional
economy, actions of the Federal government and other factors, have created
structural budget gaps for the State. These gaps resulted from a significant
disparity between recurring revenues and the cost of maintaining or increasing
the level of support for State programs. The 1995-96 enacted budget combines
significant tax and program reductions which will, in the current and future
years, lower both the recurring receipts base (before the effect of any economic
stimulus from such tax reductions) and the historical annual growth in state
program spending. Notwithstanding these changes, the State can expect to
continue to confront structural deficits in future years.
 
    The 1995-96 State Financial Plan includes actions that will have an effect
on the budget outlook for State fiscal year 1996-97 and beyond. The net amount
of nonrecurring resources used in the 1995-96 State Financial Plan is estimated
by the Division of the Budget at over $600 million. In addition to this use of
nonrecurring resources, the 1995-96 State Financial Plan reflects actions that
will directly affect the State's 1996-97 fiscal year baseline receipts and
disbursements. The three-year plan to reduce State personal income taxes will
decrease State tax receipts by an estimated $1.7 billion in State fiscal year
1996-97, in addition to the amount of reduction in State fiscal year 1995-96.
Further significant reductions in the personal income tax are scheduled for the
1997-98 State fiscal year. Other tax reductions enacted in 1994 and 1995 are
estimated to cause an additional reduction in receipts of over $500 million in
1996-97, as compared to the level of receipts in 1995-96. Similarly, many
actions taken to reduce disbursements in the State's 1995-96 fiscal year are
expected to provide greater reductions in State fiscal year 1996-97. These
include actions to reduce the State work force, reduce Medicaid and welfare
expenditures and slow community mental hygiene program development.
 
    The net impact of these and other factors is expected to produce a potential
imbalance in receipts and disbursements in State fiscal year 1996-97. The
Governor has indicated that in the 1996-97 Executive Budget he will propose to
close this potential imbalance primarily through General Fund expenditure
reductions and without increases in taxes or deferrals of scheduled tax
reductions.
 
    To address a potential imbalance in any given fiscal year, the State would
be required to take actions to increase receipts and/or reduce disbursements as
it enacts the budget for that year, and under the State Constitution, the
Governor is required to propose a balanced budget each year. To correct
recurring budgetary imbalances, the State would need to take significant actions
to align recurring receipts and disbursements in future fiscal years. There can
be no assurance, however that the Legislature will enact the Governor's
proposals or that the State's actions will be sufficient to preserve budgetary
balance in a given fiscal year or to align recurring receipts and disbursements
in future fiscal years.
 
    The State is a defendant in numerous legal proceedings and the monetary
damages sought are substantial. These proceedings could affect adversely the
financial condition of the State in the 1995-96 fiscal year or thereafter.
 
    The economic and financial condition of the State may be affected by various
financial, social, economic and political factors. Those factors can be very
complex, can vary from fiscal year to fiscal year, and are frequently the result
of actions taken not only by the State but also by entities, such as the federal
government, that are outside the State's control. Because of the uncertainty and
unpredictability of changes in these factors, their impact cannot be fully
included in the assumptions underlying the State's projections. There can be no
assurance that the State economy will not experience results that are worse than
predicted, with corresponding material and adverse effects on the State's
financial projections.
 
    From time to time, Federal expenditure reductions could reduce, or in some
cases eliminate, Federal funding of some local programs and accordingly might
impose substantial increased expenditure requirements on affected localities. If
the State, the City or any of the public authorities were to suffer serious
financial difficulties jeopardizing their respective access to the public credit
markets, the marketability of notes and bonds issued by localities within the
State could be
                                      A-xi
 
<PAGE>
adversely affected. Localities also face anticipated and potential problems
resulting from certain pending litigation, judicial decisions and long-range
economic trends. Long-range potential problems of declining urban population,
increasing expenditures and other economic trends could adversely affect
localities and require increasing State assistance in the future.
 
   New York City
 
    The fiscal health of the State is closely related to the fiscal health of
its localities, particularly The City of New York (the 'City'), which has
required and continues to require significant financial assistance from the
State which financial assistance could be affected by State revenue short-falls
or spending increases beyond its projections. For each of its 1981 through 1995
fiscal years, the City, as required by State law, achieved balanced operating
results, in accordance with GAAP.
 
    The New York State Financial Emergency Act for The City of New York (the
'Financial Emergency Act'), among other things, established the New York State
Financial Control Board (the 'Control Board') to oversee the City's financial
affairs. The City operates under a four-year financial plan which is prepared
annually and is updated quarterly. The City submits its financial plans as well
as the updates quarterly to the Control Board for its review. The Municipal
Assistance Corporation for The City of New York ('MAC') and the Office of the
State Deputy Comptroller for The City of New York ('OSDC') assist the Control
Board in exercising its powers and responsibilities and exercise various
monitoring functions relating to the City's financial position.
 
    During recent fiscal years, as a result of the slowing economy, the City
experienced significant shortfalls from earlier projections in almost all of its
major tax sources, and was required to take exceptional measures to close
substantial budget gaps in order to maintain balanced budgets. There can be no
assurance that the City will continue to maintain a balanced budget as required
by State law without additional tax or other revenue increases or additional
reductions in City services or entitlement programs, which could adversely
affect the City's economic base. The City's Financial Plan for the 1996-99
fiscal years, sets forth actions to close a projected budget gap of $3.1 billion
for the 1996 fiscal year. The Financial Plan also outlines projected budget gaps
of $2.0 billion, $3.3 billion and $4.1 billion for the 1997 through 1999 fiscal
years, respectively.
 
    As of June 30, 1995, the City estimated that its potential future liability
on account of outstanding claims against it amounted to approximately $2.5
billion and while the outcome of the proceedings and claims are not currently
predictable, adverse determinations in certain of them might have a material
adverse effect upon the City's ability to carry out the 1996-1999 Financial
Plan.
 
    On July 10, 1995, Standard and Poor's revised its rating of City bonds
downward to 'BBB+' and continued its negative rating outlook assessment. In
February 1991, Moody's Investors Service lowered its rating on the City's
general obligation bonds from 'A' to 'Baa1.'
 
    Over the long term, serious potential economic problems may continue to
aggravate State and local financial conditions. For decades, the State economy
has grown more slowly than the nation as a whole, resulting in the gradual
erosion of the State's relative economic affluence and tax base, and the
relocation of certain manufacturing operations and executive offices outside the
State. The causes of this relative decline are varied and complex, in many cases
involving national and international developments beyond the State's control.
Part of the reason for the long-term relative decline in the State economy has
been attributed to the combined state and local tax burden, which is among the
highest in the nation. The existence of this tax burden limits the State's
ability to impose higher taxes in the event of future financial difficulties.
 
    If during the existence of the New York Trust, the City, the State, or any
of its agencies or municipalities, because of its or their own financial
difficulties, become unable to meet regular commitments or if there should be a
default, moratorium or other interruption of payments of interest or principal
on any obligation issued by the City, the State, or a municipality or other
authority in New York State, the market value and marketability of Bonds in the
New York Trust, the asset value of Units of the New York Trust and the interest
income to the New York Trust, could be adversely affected.

<PAGE>
                        SUPPLEMENT TO PART B--TAX STATUS
 
California Trust
 
    On the Date of Deposit, special California counsel for the Sponsor rendered
an opinion under the then existing California state income tax law which read as
follows:
 
        The Insured Trust is not an association taxable as a corporation under
    the income tax laws of the State of California;
 
        The income, deductions and credits against tax of the Insured Trust will
    be treated as the income, deductions and credits against tax of the holders
    of Units in the Insured Trust under the income tax laws of the State of
    California;
 
        Interest on the bonds held by the Insured Trust to the extent that such
    interest is exempt from taxation under California law will not lose its
    character as tax-exempt income merely because that income is passed through
    to the holders of Units; however, a corporation subject to the California
    franchise tax is required to include that interest income in its gross
    income for purposes of determining its franchise tax liability;
 
        Each holder of a Unit in the Insured Trust will have a taxable event
    when the Insured Trust disposes of a bond (whether by sale, exchange,
    redemption, or payment at maturity) or when the Unit holder redeems or sells
    his Units. The total tax cost of each Unit to a holder of a Unit in the
    Insured Trust is allocated among each of the bond issues held in the Insured
    Trust (in accordance with the proportion of the Insured Trust comprised by
    each bond issue) in order to determine the holder's per Unit tax cost for
    each bond issue, and the tax cost reduction requirements relating to
    amortization of bond premium will apply separately to the per Unit tax cost
    of each bond issue. Therefore, under some circumstances, a holder of a Unit
    may realize taxable gain when the Insured Trust disposes of a bond or the
    holder's Units are sold or redeemed for an amount equal to or less than his
    original cost of the bond or Unit;
 
        Each holder of a Unit in the Insured Trust is deemed to be the owner of
    a pro rata portion of the Insured Trust under the personal property tax laws
    of the State of California;
 
        Each Unit holder's pro rata ownership of the bonds held by the Insured
    Trust, as well as the interest income therefrom, is exempt from California
    personal property taxes; and
 
        Amounts paid in lieu of interest on defaulted bonds held by the Trustee
    under policies of insurance issued with respect to such bonds will be
    excludable from gross income for California income tax purposes if, and to
    the same extent as, those amounts would have been so excludable if paid as
    interest by the respective issuer.
 
    In the opinion of Messrs. Kopesky & Welke, LLP, special California counsel
to the Sponsor, no change in law has occurred since the Date of Deposit which
would require a change in the above opinion.
 
New York Tax Status
 
    In the opinion of Messrs. Cahill Gordon & Reindel, special New York counsel
on New York tax matters, as of the date of this Prospectus, under existing law:
 
        Interest on the underlying debt obligations which is exempt from tax
    under the laws of the State and City of New York when received by the New
    York Trust will retain its status as tax-exempt interest to its Unit
    Holders. (Interest on the underlying obligations in the New York Trust is,
    however, not excludable from income in determining the amount of the
    income-based (i) New York State franchise taxes on business and financial
    corporations or (ii) the New York City general corporation tax and the New
    York City financial corporation tax.) The minimum income taxes imposed by
    New York State and New York City on individuals, estates and trusts exclude
    from their taxable bases the Federal tax preference item with respect to
    tax-exempt interest.
 
        Non-residents of New York City will not be subject to the City personal
    income tax on gains derived with respect to their Units. Non-residents of
    the State will not be subject to New York State personal income tax on such
    gains unless the Units are employed in a business, trade or occupation
    carried on in New York State. A New York State or City resident should
    determine his basis and holding period for his Units in the same manner for
    New York State and City personal income tax purposes as for Federal income
    tax purposes.

<AUDIT-REPORT>

                        INDEPENDENT AUDITORS' REPORT

THE UNIT HOLDERS, SPONSOR AND TRUSTEE
NATIONAL MUNICIPAL TRUST,
SERIES 160 (Uninsured)
MULTISTATE SERIES 59 consisting of:
  CALIFORNIA TRUST (Insured)
  NEW YORK TRUST (Insured)

We have audited the statements of financial condition and schedules of 
portfolio securities of the National Municipal Trust Series 160 (Uninsured) 
and Multistate Series 59 consisting of the California Trust (Insured) and 
the New York Trust (Insured) as of April 30, 1997, and the related 
statements of operations and changes in net assets for the three years in 
the period then ended.  These financial statements are the responsibility of 
the Trustee (see Footnote (a)(1)).  Our responsibility is to express an 
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
Our procedures included confirmation of the securities owned as of April 30, 
1997 as shown in the statements of financial condition and schedules of 
portfolio securities by correspondence with The Chase Manhattan Bank, the 
Trustee.  An audit also includes assessing the accounting principles used 
and the significant estimates made by the Trustee, as well as evaluating the 
overall financial statement presentation.  We believe that our audits 
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, 
in all material respects, the financial position of the National Municipal

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Trust is registered under the Investment Company Act of 1940 as a 
Unit Investment Trust.  The following is a summary of the significant 
accounting policies of the Trust:

(1) Basis of Presentation

    The Trustee has custody of and responsibility for all accounting and 
financial books, records, financial statements and related data of 
the Trust and is responsible for establishing and maintaining a 
system of internal controls directly related to, and designed to 
provide reasonable assurance as to the integrity and reliability 
of, financial reporting of the Trust.  The Trustee is also 
responsible for all estimates and accruals reflected in the Trust's 
financial statements.  The Evaluator determines the price for each 
underlying Security included in the Trust's Schedule of Portfolio 
Securities on the basis set forth in Part B of this Prospectus, 
"Public Offering of Units - Public Offering Price".  Under the 
Securities Act of 1933 ("the Act"), as amended, the Sponsor is 
deemed to be an issuer of the Trust Units.  As such, the Sponsor 
has the responsibility of an issuer under the Act with respect to 
financial statements of each Trust included in the Registration 
Statement under the Act and amendments thereto.

(2) Investments

    Investments are stated at market value as determined by the 
Evaluator based on the bid side evaluations on the last day of 
trading during the period, except that value on the date of deposit 
(May 19, 1993) represents the cost of investments to the Trust 
based on the offering side evaluations as of the date of deposit.

(3) Income Taxes

    The trust is not an association taxable as a corporation for Federal 
income tax purposes; accordingly, no provision is required for such 
taxes.

(4) Expenses

    The Trust pays an annual Trustee's fee, estimated expenses, 
Evaluator's fee and an annual Sponsor portfolio supervision fee  
and may incur additional charges as explained under "Expenses and 
Charges - Fees" and "- Other Charges" in Part B of this Prospectus.

(b) DISTRIBUTIONS

    Interest received by the Trust is distributed to the Unit Holders on or 
shortly after the twenty-fifth day of each month after deducting 
applicable expenses.  Receipts other than interest are distributed as 
explained in "Rights of Unit Holders - Distribution of Interest and 
Principal" in Part B of this Prospectus.

(c) ORIGINAL COST TO INVESTORS

    The original cost to investors represents the aggregate initial public 
offering price as of the date of deposit (May 19, 1993) exclusive of 
accrued interest.


    A reconciliation of the original cost of Units to investors to the net 
amount applicable to investors as of April 30, 1997 follows:

<F1> All ratings are provided by Standard & Poor's Corporation, unless 
otherwise indicated.  A brief description of applicable Security 
ratings is given under "Bond Ratings" in Part B of this Prospectus.

<F2> There is shown under this heading the date on which each issue of 
Securities is redeemable by the operation of optional call 
provisions and the redemption price for that date; unless otherwise 
indicated, each issue continues to be redeemable at declining 
prices thereafter but not below par.  Securities listed as non-
callable, as well as Securities listed as callable, may also be 
redeemable at par under certain circumstances from special 
redemption payments.

<F3> There is shown under this heading the date on which an issue of 
Securities is subject to scheduled sinking fund redemption and the 
redemption price on such date.

<F4> The market value of the Securities as of April 30, 1997 was 
determined by the Evaluator on the basis of bid side evaluations 
for the Securities on that date.

<F5> At April 30, 1997, the net unrealized market appreciation of all 
Securities was comprised of the following:

<TABLE>
       <S>                                          <C>
       Gross unrealized market appreciation         $126,874
       Gross unrealized market depreciation          (65,700)
       Net unrealized market appreciation           $ 61,174
</TABLE>

    The amortized cost of the Securities for Federal income tax purposes 
was $7,789,996 at April 30, 1997.

<F6> In the opinion of bond counsel to the issuing governmental 
authorities, interest payments on these bonds will be a tax 
preference item for individuals and corporations for alternative 
minimum tax purposes.  Normally, the bonds pay interest 
semiannually.  The payment dates can generally be determined based 
on the date of maturity, i.e., a bond maturing on December 1 will 
pay interest semiannually on June 1 and December 1.  See "Tax 
Status" in Part B of this Prospectus.

<F7> Moody's Investors Service, Inc. Rating.

<F8> Insurance to maturity has been obtained by the issuer from the 
listed Insurance Company.  The "AAA" rating on this Security is 
based in part on the credit worthiness and claims-paying ability of 
the Insurance Company issuing such Security to maturity.

<F9> The Issuer of Portfolio No. 7 has indicated that it will refund this 
Security on its optional redemption date.

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Trust is registered under the Investment Company Act of 1940 as a 
Unit Investment Trust.  The following is a summary of the significant 
accounting policies of the Trust:

(1) Basis of Presentation

    The Trust has custody of and responsibility for all accounting and 
financial books, records, financial statements and related data of 
the Trust and is responsible for establishing and maintaining a 
system of internal controls directly related to, and designed to 
provide reasonable assurance as to the integrity and reliability 
of, financial reporting of the Trust.  The Trustee is also 
responsible for all estimates and accruals reflected in Trust's 
financial statements.  The Evaluator determines the price for each 
underlying Security included in the Trust's Schedule of Portfolio 
Securities on the basis set forth in Part B of this Prospectus, 
"Public Offering of Units - Public Offering Price".  Under the 
Securities Act of 1933 ("the Act"), as amended, the Sponsor is 
deemed to be an issuer of the Trust Units.  As such, the Sponsor 
has the responsibility of an issuer under the Act with respect to 
financial statements of each Trust included in the Registration 
Statement under the Act and amendments thereto.

(2) Investments

    Investments are stated at market value as determined by the 
Evaluator based on the bid side evaluations on the last day of 
trading during the period, except that value on the date of deposit 
(May 19, 1993) represents the cost of investments to the Trust 
based on the offering side evaluations as of the date of deposit.

(3) Income Taxes

    The Trust is not an association taxable as a corporation for Federal 
income tax purposes; accordingly, no provision is required for such 
taxes.

(4) Expenses

    The Trust pays an annual Trustee's fee, estimated expenses, 
Evaluator's fee, and an annual Sponsor portfolio supervision fee  
and may incur additional charges as explained under "Expenses and 
Charges - Fees" and "- Other Charges" in Part B of this Prospectus.

(b) DISTRIBUTIONS

    Interest received by the Trust is distributed to the Unit Holders on or 
shortly after the twenty-fifth day of each month after deducting 
applicable expenses.  Receipts other than interest are distributed as 
explained in "Rights of Unit Holders - Distribution of Interest and 
Principal" in Part B of this Prospectus.

    The original cost to investors represents the aggregate initial public 
offering price as of the date of deposit (May 19, 1993) exclusive of 
accrued interest.

amount applicable to investors as of April 30, 1997 follows:

<F10> All ratings are provided by Standard & Poor's Corporation.  A brief 
description of applicable Security ratings is given under "Bond 
Ratings" in Part B of this Prospectus.

<F11> There is shown under this heading the date on which each issue of 
Securities is redeemable by the operation of optional call 
provisions and the redemption price for that date; unless otherwise 
indicated, each issue continues to be redeemable at declining 
prices thereafter but not below par.  Securities listed as non-
callable, as well as Securities listed as callable, may also be 
redeemable at par under certain circumstances from special 
redemption payments.

<F12> There is shown under this heading the date on which an issue of 
Securities is subject to scheduled sinking fund redemption and the 
redemption price on such date.

<F13> The market value of the Securities as of April 30, 1997 was 
determined by the Evaluator on the basis of bid side evaluations 
for the Securities on that date.

<F14> At April 30, 1997, the unrealized market appreciation of all 
Securities was comprised of the following:

<TABLE>
       <S>                                           <C>
       Gross unrealized market appreciation          $11,035
       Gross unrealized market depreciation             -   
       Unrealized market appreciation                $11,035
</TABLE>

    The aggregate cost of the Securities for Federal income tax purposes 
was $2,400,797 at April 30, 1997.

<F15> Insurance to maturity has been obtained by the Issuer from the 
listed Insurance Company.  The "AAA" ratings on these Securities 
are based in part on the credit worthiness and claims-paying 
ability of the Insurance Company insuring such Security to 
maturity.  No premium is payable therefore by the Trust.

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Trust is registered under the Investment Company Act of 1940 as a 
Unit Investment Trust.  The following is a summary of the significant 
accounting policies of the Trust:

(1) Basis of Presentation

    The Trustee has custody of and responsibility for all accounting and 
financial books, records, financial statements and related data of 
the Trust and is responsible for establishing and maintaining a 
system of internal controls directly related to, and designed to 
provide reasonable assurance as to the integrity and reliability 
of, financial reporting of the Trust.  The Trust is also 
responsible for all estimates and accruals reflected in the Trust's 
financial statements.  The Evaluator determines the price for each 
underlying Security included in the Trust's Schedule of Portfolio 
Securities on the basis set forth in Part B of this Prospectus, 
"Public Offering of Units - Public Offering Price".  Under the 
Securities Act of 1933 ("the Act"), as amended, the Sponsor is 
deemed to be an issuer of the Trust Units.  As such, the Sponsor 
has the responsibility of an issuer under the Act with respect to 
financial statements of each Trust included in the Registration 
Statement under the Act and amendments thereto.

(2) Investments

    Investments are stated at market value as determined by the 
Evaluator based on the bid side evaluations on the last day of 
trading during the period, except that value on the date of deposit 
(May 19, 1993) represents the cost of investments to the Trust 
based on the offering side evaluations as of the date of deposit.

(3) Income Taxes

    The Trust is not an association taxable as a corporation for Federal 
income tax purposes; accordingly, no provision is required for such 
taxes.

(4) Expenses

    The Trust pays an annual Trustee's fee, estimated expenses, 
Evaluator's fees and an annual Sponsor portfolio supervision fee  
and may incur additional charges as explained under "Expenses and 
Charges - Fees" and "- Other Charges" in Part B of this Prospectus.

(b) DISTRIBUTIONS

    Interest received by the Trust is distributed to the Unit Holders on or 
shortly after the twenty-fifth day of each month after deducting 
applicable expenses.  Receipts other than interest are distributed as 
explained in "Rights of Unit Holders - Distribution of Interest and 
Principal" in Part B of this Prospectus.

(c) ORIGINAL COST TO INVESTORS

    The original cost to investors represents the aggregate initial public 
offering price as of the date of deposit (May 19, 1993) exclusive of 
accrued interest.


    A reconciliation of the original cost of Units to investors to the net 
amount applicable to investors as of April 30, 1997 follows:

<F16> All ratings are provided by Standard & Poor's Corporation.  A brief 
description of applicable Security ratings is given under "Bond 
Ratings" in Part B of this Prospectus.

<F17> There is shown under this heading the date on which each issue of 
Securities is redeemable by the operation of optional call 
provisions and the redemption price for that date; unless otherwise 
indicated, each issue continues to be redeemable at declining 
prices thereafter but not below par.  Securities listed as non-
callable, as well as Securities listed as callable, may also be 
redeemable at par under certain circumstances from special 
redemption payments.

<F18> There is shown under this heading the date on which an issue of 
Securities is subject to scheduled sinking fund redemption and the 
redemption price on such date.

<F19> The market value of the Securities as of April 30, 1997 was 
determined by the Evaluator on the basis of bid side evaluations 
for the Securities on that date.

<F20> At April 30, 1997, the net unrealized market appreciation of all 
Securities was comprised of the following:

<TABLE>
       <S>                                            <C>
       Gross unrealized market appreciation           $9,883
       Gross unrealized market depreciation           (4,496)
       Net unrealized market appreciation             $5,387
</TABLE>

    The aggregate cost of the Securities for Federal income tax purposes 
was $3,197,250 at April 30, 1997.

<F21> Insurance to maturity has been obtained by the Issuer from the 
listed Insurance Company.  The "AAA" ratings on these Securities 
are based in part on the creditworthiness and claims-paying ability 
of the Insurance Company insuring such Security to maturity.  No 
premium is payable therefore by the Trust.

                    Multistate Series 59

Gentlemen:

          Pursuant to your request, we have reviewed the opinion included
in the Prospectus for the captioned Series expressed by prior California
counsel to the Sponsor regarding the California income and property tax
status of the above-captioned Series of the National Municipal Trust.  We
are of the opinion that such opinion, a copy of which is included in the
Prospectus for the above-captioned Series, remains valid and that no change
has occurred which would require a change to such opinion and you may rely
on it in connection with the filing of a Post Effective Amendment to such
Series.

          We consent to the use of our name under the caption "Supplement
to Part B - Tax Status" in the Prospectus comprising a part of the above-
captioned Post Effective Amendment and we consent to the filing of this
opinion as an exhibit to said Post Effective Amendment.

                                   Very truly yours,

                                   Kopesky & Welke
