The Presidential Issue, nicknamed the Prexies by collectors, is the series of definitive postage stamps issued in the United States in 1938, featuring all 29 U.S. presidents who were in office between 1789 and 1928, from George Washington to Calvin Coolidge. The presidents appear as small profile busts printed in solid-color designs through 50¢, and then as black on white images surrounded by colored lettering and ornamentation for $1, $2, and $5 values. Additional stamps in fractional-cent denominations offer busts of Benjamin Franklin and Martha Washington, as well as an engraving of the White House. With its total of 32 stamps, this was the largest definitive series yet issued by the U. S. Post Office.
In 1933 President Franklin D. Roosevelt, himself a serious stamp collector, fostered the idea of a set of stamps honoring all the deceased past presidents of the United States. A national contest was held in 1937 to choose a designer for the first stamp of the series, the 1-cent George Washington issue. More than eleven hundred entries were submitted, some from famous artists. An artist from New York, Elaine Rawlinson, won the contest. Her design for the 1-cent stamp showed Washington in profile, modeled after a bust by the famous sculptor Jean-Antoine Houdon, and became the template for the new definitive series issued in 1938.[1]
