Betty Boop's 1933 "Halloween Party" wasn't really banned. The person who posted this video to YouTube was looking for click bait from curious viewers. Instead, it's the Fleischers at their most surreal. Who else would have paintings of witches come to life to scare off a party-crashing gorilla?
Silly, harmless fun. That's all it is. They just don't make cartoons like this anymore.
