Insignias During World War II, Walt Disney was asked by various military units to design insignias that they could put on their planes, jackets, and ships. Over 1, 200 of these insignias were produced, many containing Disney characters, but occasionally, as with the Flying Tigers, the units already had a character in mind. Donald Duck was perhaps the most requested character, appearing on several hundred insignias. Mickey Mouse, being a less-warlike figure, was used only rarely, and then for such units as signal corps and chaplains corps. The drawings were prepared by several Disney artists, led by Hank Porter and Roy Williams. Walt provided these insignias to the units without charge as part of his donation to the war effort. Other animation studios in Hollywood were also called upon for insignias, and during the war, many of the Disney and non-Disney insignias were published on poster stamps for affixing in albums supplied by local newspapers.
