While I still have the MGM Animation/Visual Arts file handy, what do you make of this? It's drawn by my father, some of it on official MGM board paper. To my own knowledge MGM never issued a B.C. animated cartoon, although some of you might know different. Maybe it was a test that B.C.'s creator, Johnny Hart, vetoed. In this era MGM was co-opting the material of others -- Ted Geisel (Seuss), Tashlin (Bear That Wasn't) and Juster (Phantom Tollbooth), to name a few. In any event, to my memory, some of it looks like a straight rip from the actual strip.
Here are the type of drawings dear to my heart. Again at MGM, the inside innuendo stuff that cartoonists pass among themselves. Not knowing exactly what was happening at any particular moment which caused one cartoonist to playfully jab another, it's tough to say who drew what, and for what reason...but who cares. You'll notice a couple of recurring artists depicted.
