Uncle Sam's Hat 2017 Additional Ounce Postage Stamps Self-Adhesive Sheet for Extra Postage

Uncle Sam was first illustrated as we know him today during World War I.  His most famous appearance was on a recruitment poster created by James Montgomery Flagg.  It featured a stern image of Uncle Sam declaring, “I Want YOU For U.S. Army.”  The poster was printed over four million times and was so successful that it is still a national icon over 100 years later.

Thanks to Nast and Flagg’s illustrations, Uncle Sam has become instantly recognizable to every American.  As long as the U.S. holds true to the values he represents – liberty, justice, and equality for all – Uncle Sam will always be a symbol of the American spirit.
