Uncle Sam is a national personification of the United States, with the first usage of the term dating from the War of 1812 and the first illustration dating from 1852. He is often depicted as a serious elderly man with white hair and a goatee, dressed in clothing that recalls the design elements of the flag of the United States—for example, a top hat with red and white stripes and white stars on a blue band, and red and white pants.
Uncle Sam Imagery
Thomas Nast played an important role in creating the popular image of Uncle Sam in his post-Civil War era editorial cartoons. After the American Civil War, whiskers were added to Uncle Sam in reference to Abraham Lincoln. Today, with the possible exception of the Statue of Liberty, the character of Uncle Sam is probably the most easily recognizable personification of the U.S.
World War I poster
During World War I, a very famous poster, inspired by a British recruitment poster, depicted Uncle Sam pointing at the people with the words I WANT YOU FOR U.S. ARMY. The artist James Montgomery Flagg, who painted the poster in 1917, used a modified version of his own face for Uncle Sam.[2] Veteran Walter Botts posed for the drawing that became Uncle Sam. The poster was based on a 1914 recruitment poster from Britain featuring Lord Kitchener, which was designed by Alfred Leete.
