The Board of Trustees and Shareholders of
Oppenheimer Municipal Bond Fund:
In planning and performing our audit of the financial statements of Oppenheimer
Municipal Bond Fund (formerly Oppenheimer Tax-Free Bond Fund) for the year ended
July 31, 1997, we considered its internal control structure, including
procedures for safeguarding securities, in order to determine our auditing
procedures for the purpose of expressing our opinion on the financial statements
and to comply with the requirements of Form N-SAR, not to provide assurance on
the internal control structure.
The management of Oppenheimer Municipal Bond Fund is responsible for
establishing and maintaining an internal control structure. In fulfilling this
responsibility, estimates and judgments by management are required to assess the
expected benefits and related costs of internal control structure policies and
procedures. Two of the objectives of an internal control structure are to
provide management with reasonable, but not absolute, assurance that assets are
safeguarded against loss from unauthorized use or disposition and that
transactions are executed in accordance with management's authorization and
recorded properly to permit preparation of financial statements in conformity
with generally accepted accounting principles.
Because of inherent limitations in any internal control structure, errors or
irregularities may occur and may not be detected. Also, projection of any
evaluation of the structure to future periods is subject to the risk that it may
become inadequate because of changes in conditions or that the effectiveness of
the design and operation may deteriorate.
Our consideration of the internal control structure would not necessarily
disclose all matters in the internal control structure that might be material
weaknesses under standards established by the American Institute of Certified
Public Accountants. A material weakness is a condition in which the design or
operation of the specific internal control structure elements does not reduce to
a relatively low level the risk that errors or irregularities in amounts that
would be material in relation to the financial statements being audited may
occur and not be detected within a timely period by employees in the normal
course of performing their assigned functions. However, we noted no matters
involving the internal control structure, including procedures for safeguarding
securities, that we considered to be material weaknesses as defined above as of
July 31, 1997.
This report is intended solely for the information and use of management and the
Securities and Exchange Commission and should not be used for any other purpose.

During the year ended July 31, 1997, the Fund adjusted the classification of
distributions to shareholders to reflect the differences between financial
statement amounts and distributions determined in accordance with income tax
regulations. Accordingly, during the year ended July 31, 1997, amounts have been
reclassified to reflect a decrease in paid-in capital of $11,664, a decrease in
undistributed net investment income of $730,353, and an increase in accumulated
net realized gain on investments of $742,017.
