Uncle Sam is a common personification of the American government that, according to legend, came into use during the War of 1812 and was supposedly named for Samuel Wilson. The first use of Uncle Sam in literature was in the 1816 allegorical book "The Adventures of Uncle Sam in Search After His Lost Honor" by Frederick Augustus Fidfaddy, Esq. An Uncle Sam is mentioned as early as 1775, in the original "Yankee Doodle" lyrics of the Revolutionary War. The image of Uncle Sam was shown publicly for the first time, according to some, in a picture by Flagg on the cover of the magazine Leslie's Weekly, on July 6, 1916, with the caption "What Are You Doing for Preparedness?" More than four million copies of this image were printed between 1917 and 1918.
