If you served in the Army, you might as well have a little piece of Army history by hanging up this historic Uncle Sam recruiting metal poster. During the First World War, artist James Montgomery Flagg designed 46 posters for the government. His most famous work is the Uncle Sam poster with the caption "I Want You for the U.S. Army". An adapted version of this poster was also used during the Second World War. This USA-made metal sign measures 12.5" by 16".
