Ollie Johnston animated this sequence, which introduces the comic villain and his sidekick snake.
Somehow the pencil test seems to reveal more subtleties in the animation than the final color footage, most of us are used to.
This is clean up animation, Ollie's original roughs were a bit looser. Also, Prince John's crown with all its diamonds was finalized by an effects animator. Ollie just drew the main shape of it.
What beautiful dimensional animation!
Pardon the picture quality here, this was part of an old TV show from the early 1970ies.
The clip starts out with the story reel version, and it looks like Ken Anderson drew those sketches.
