Toons At War is an excellent exposé of Walt Disney’s contributions to the Second World War effort. It shows graphics for military and civilian consumption as well as government driven civil programmes.
The U.S. government enabled the Disney studio to have “a good war”.
UPDATE: The author of the Toons at War blog has commented: –
Disney’s was the only major Hollywood Studio to have had a military unit stationed on its property during the war.
The day after the Japanese attack on Pearl Harbor, an anti-aircraft unit forcibly moved their men and equipment into many of the Disney Studio’s buildings, even going so far as to store several million rounds of ammunition under the sheds in the parking lot.
Disney created a lot of war-related product for various federal, state and local governments as well as many non-profit agencies like the L.A. War Chest and the United China Relief Fund. A lot of material was produced at no cost while most of the government work was billed with no mark-up for profit.
This war-related work helped the Studio survive at a time when overseas markets, which accounted for a huge amount of the Studio’s revenue, were closed as the Nazis marched across the European continent. If I recall correctly, by 1944 roughly 80% of the Studio’s revenue was being generated by just three countries: the USA, Canada and Mexico.
