This will only be of interest to folks obsessed with comic books and animation art. The rest of you can skip on to the next item.
In 1978, Hanna-Barbera had a short-lived cartoon show called The C.B. Bears. In connection with it, a coloring book was done. He didn't work on the cover but all of the interiors were done by one rather famous (in this field) artist. His name appeared nowhere on the book and as far as I know, I'm the only person alive who knows he drew this…and only because he told me and showed me some of the pages he was working on. You can see a few more interior pages below and over at this site which likes to scan pages out of old coloring books.
It's rather an unusual assignment for this gentleman…and no, it isn't Jack Kirby. Anyone want to guess who it is? I'll post the answer in twenty-four hours and credit the first three people who get it, assuming three people get it.
