Franklin D. Roosevelt's "Farley's Follies": One the of the first things President Franklin Roosevelt did upon being elected president in 1932 was to appoint his campaign manager, New York politician James A. Farley, as his Postmaster General. Farley, in order to please the president, immediately embarked upon a policy of giving his boss full uncut (and imperforate) sheets of each new stamp issue just before they were to be released. In addition, Farley would also be generous with other luminaries in the FDR administration by giving similar sheets to some of his and FDR's friends and cabinet members.

When stamp collectors found out about this favoritism, they began to holler loudly that FDR and Farley had created special issues for their friends...with items that would never reach the hands of the public. The issue was even debated in Congress and, together with pressure from the general public (and most particularly, philatelists), Farley was urged to do something to right this wrong. So...in 1935 (Scott Nos. 752-771 inclusive), Farley re-issued all of the uncut, imperforate sheets (mostly representing the National Parks issue of 1943) to the general public.
