I did a post about Cathedral Films back in 2007 when we found a connection between this religious film strip producer and Bill Hanna and Gene Hazelton. Filmstrips are still in a side-alley of animation history that has yet to be explored. Artists from MGM, Disney and others worked on these after hours. Here’s another filmstrip somebody posted in its entirety on the internet, and artwork here is pretty good (note Paul Frees as the voice of the ocean). Anyone recognize the art style?
