The Walt Disney insignia painting, which features a woman in uniform patching an inflatable tube, is rendered in gouache on illustration board (8.5 x 10.5") and is housed in a Walt Disney Productions mailing envelope addressed to Wynne Gibson. In his article "When Disney Went to War" for Smithsonian Magazine, John Baxter observes, "One of the purest expressions of Walt Disney's genuine patriotism during the war years was his decision to establish a unit devoted to producing customized military unit insignia free of charge for U.S. armed forces and their allies. Headed by the talented draftsman Hank Porter, whom Walt referred to as a 'one-man art department,' the unit worked steadily throughout the war, turning out nearly 1,300 insignia upon request."
