This is Zadoc. I don’t know for sure who drew him — on a piece of animation paper — but he’s a very Dick Huemeresque character, particularly in the way he’s waving his ginormous hands about. And he looks like he’s the love child of Scrappy and Harpo Marx.
He may have appeared in a Mintz cartoon I don’t know about. Or maybe he never got off the drawing board. Anyone know anything about him?
