The Modern Mechanix blog has posted an article from a 1938 issue of Popular Science. It's about John Czeski, an Ohio farmer who made human pumpkin heads. That is, Czeski made a mold of the entire human head he wanted to reproduce. He would then set it over a young pumpkin. Once the pumpkin filled in the contours, the mold was removed.
This was so effective, it's almost fakey looking. (Hey, how do you spell that: "fakey"? "fakie"?)
How far have we come in anthropomorphic gourd technology in the following 70 years? Well, this guy grew a pumpkin with Mickey Mouse ears. Humph.
