So I have no idea where this is from, though I know it’s pretty famous and I’ve seen it before. I’m also not sure who the artist is so I’ll guess Wayne Boring. I’m sure someone will know for sure.
The larger version is over here.
And I know this is Jack Kirby but I’m not sure where it’s from. There was a Kirby pin-up of The Beast on the blog last month.
Anyway, the larger version of Marvel Girl can be found over here.
