Imagine how much cheaper car assembly would be with no workers. No healthcare costs! No strikes! The pistons, they just march right in to that ol' flathead six!
That's what we see in this high-production-value stop-motion film made for the 1939 New York World's Fair. Just come to the "Frozen Forest" or the "Bamboo Grove" to see the latest Chryslers, Dodges, and DeSotos!
