Dear Mr. Joyce,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series General Correspondence, 1917-1958 in the Records of the U.S. Military Academy (Record Group 404) that includes administrative files and correspondence of multiple academy officials and that may contain the request you are seeking. These records have not been digitized. For access to these and similar records, please contact the United States Military Academy Archives (an affiliated archives) (XUSMA) at Library@westpoint.edu.
Next, we located 4 series of personal papers and diaries that contain records related to Douglas MacArthur in the 1930s in the custody of the Dwight D. Eisenhower Library (LP-DDE) that may include the directive from MacArthur. These records have not been digitized. Please contact LP-DDE at email@example.com for more information about these records.
Plus, we located the series Security Classified General Correspondence, 1920-1942 for the Office of the Chief of Staff in the Records of the War Department General and Special Staffs (Record Group 165) that may be useful. This series is indexed by the series Subject Card Index, 1920-1942 in Record Group 165. The series Central Correspondence File, 1881-1949 in the Records of the Bureau of Engraving and Printing (Record Group 318) contains records related to stamp design as well. These records have not been digitized. Please contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org for assistance with these and similar records.
