Uncle Sam 'I Want You' US Army Recruiting Poster
This famous poster by James Montgomery Flagg was originally published as the cover for the 6 July 1916 issue of Leslie's Weekly with the title "What Are You Doing for Preparedness?" This portrait of "Uncle Sam" went on to become one of the most famous posters in the world. Over four million copies were printed for World War I during 1917-1918, and it was again adapted for use in World War II. Flagg personally presented a copy to President Franklin Delano Roosevelt.
The figure of Uncle Sam was not invented by Flagg. The origin of the Uncle Sam idea is controversial, but is often associated with a meat packer who supplied the army during the War of 1812--Samuel (Uncle Sam) Wilson of Troy, NY.
