Uncle Sam remains one of the most powerful visual symbols of American wartime propaganda. Originally created during World War I and widely reused throughout World War II, this iconic image embodies the direct call to action directed at the American public. In 2015, collections of original U.S. propaganda posters were digitized and widely circulated, offering renewed insight into the visual strategies used to mobilize a nation at war. Today, these posters stand as enduring historical artifacts, illustrating the intersection of art, patriotism, and psychological influence during WWII. – European Center of Military History
