Max Fleischer's 1938 cartoon "All's Fair at the Fair" is a retro-futuristic look at the marvels coming to the 1939 New York World's Fair (home of the Futurama, an enormous ride-through diorama of a futuristic city with armchair ride-vehicles). The Fleischer toon shows us the fair through the eyes of a hayseed couple — one is literally chewing on a stalk of the stuff — and it has moments of genuine physical mixed in with the funny-strange look at the future past.
