By comparison the largest commemorative set previously offered by the Post Office—the landmark Columbian Exposition issue of 1893—had consisted of sixteen stamps.In January 1931 a congressman went so far as to introduce a bill (never, however, enacted) proposing that during the whole of 1932 "all postage stamps offered for sale through the United States..., of whatever color or denomination, shall bear the portrait of George Washington."While the bicentennial issue presents many unfamiliar images of Washington, the Post Office took care to place the widely loved Gilbert Stuart portrait of the president on the 2-cent stamp, which satisfied the normal first-class letter rate and would therefore get the most use.Accordingly, the Post Office felt obliged to rush a new regular issue 3-cent stamp into production that offered a more familiar Washington portrait.Rather than taking the time to create a completely new design, the BEP revamped the bicentennial 2-cent Atheneum value as a 3-cent stamp (Scott #720), transforming it into a regular issue by eliminating the date ribbons flanking the portrait.
