Title: 1971 Running Hare for TH
Description: 1971? Background and three cells for an animation of TH. $15 from 1vegaseller through Ebay, March, '21.

The seller identified this scene with Bill Cosby's Aesop, but I am unsure of that identification. As someone unacquainted with animation techniques, I find the working together of the various cell layers fascinating! The background here is so similar to that in my other group of cells that I wonder if they may not have come from the same film.
