I posted the original Bob Larkin cover art on Facebook last week. Here’s some original Dave Cockrum art from the same issue. You can read the whole comic—written by Roger McKenzie and illustrated by Ernie Colón—at Alberto’s Flickr. It’s good stuff, and there are lots of extras.
Bonus: here’s a photo of some 1978 kids transfixed by the oversized beauty.
Star-Lord’s second costume. You’ll notice that the original painting, posted at Comic Art Fans, has only Norem’s signature. The final cover has a second signature: Peter Ledger. I don’t see any differences between the two pieces, though Ledger presumably added some additional colors. Ledger also shared credit with Norem on the outstanding cover of The Hulk! #15.
