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.
