George Klein was a veteran comics artist best remembered if at all for his inks on Curt Swan's early Silver Age Superman and his rumored,maybe, possibly,
could be inks on Jack Kirby's FANTASTIC FOUR # 1. I like his work a lot...except on Gene Colan's art.
I think it's a horrible fit with Subby in particular looking like a two-dimensional animated cartoon character here...with a completely egg-shaped head with painted on black "hair." Luckily, this combination doesn't last. Looks like I wasn't the only one who thought it didn't work.
