1935 1¢ Yosemite National Park
The 1935 Yosemite Souvenir Sheet is an imperforate and ungummed reissue of the 1934 sheet printed for the Trans-Mississippi Philatelic Exposition and Convention held in Omaha, Nebraska. The original sheet was not available at general post offices.
The infamous "Farley’s Follies" controversy began in 1933 when Postmaster General James A. Farley removed several stamp sheets from the printing presses before they were gummed or perforated. He autographed these sheets (which were not available to the public) and gave them to colleagues and family, creating precious philatelic rarities. Stamp collectors were outraged when they discovered what had happened. Finally, the Post Office came up with a solution – the reissue in sheet form of all the stamps issued since March 4, 1933, in ungummed condition, all but the first two imperforate and in sufficient numbers to satisfy public demand.
