While you wait for your hamburger at Rosie's All American Cafe, you may start looking around the inside of the kitchen and notice World War II artwork throughout the restaurant. You may write the art off as mere elements of Imagineering theme but there is a Disney connection to the war that Imagineers allude to here.
During World War II, the United States government looked for help in the war effort everywhere, including Hollywood. The war effort took up so much of Walt's animators that the Disney Studio had to shut down regular production and instead created war films and patriotic cartoons to help raise the country's morale during the war.
The artwork you see inside Rosie's is actual art created by artists at the Walt Disney Studios during World War II.
