Animated horror from the 60's and 70's
I grew up in the 70's and remember watching films like "Mad Monster Party" on TV. I'm trying to come up with a list of animated films from the 60's and 70's that had a horror theme. These could even be just short 1/2 hour specials as well. They just need to be animated as cartoon or stop motion. I am hoping to possibly track some of them down for next Halloween. Can anyone suggest some titles? Even the most obscure suggestions are welcome.
