Yep.
That version of the Hulk is really all we need to complete that team and re-create that cover.
You'll note that Hulk is not (yet) a behemoth. He should be roughly the same height as Thor and Iron Man. He should also have a sloped, protruding brow and flat head like the Frankenstein monster, along with a hairy chest and three toes on each foot.
You know, Avengers wasn't supposed to come out at all. Marvel had two new titles on the schedule for June 1963: Daredevil and the Uncanny X-Men. They scheduled the books with the printer thinking they had plenty of time. Now in those days you had to pay the printing bill on the dates you reserved whether you had a book ready to print or not. So Stan had a big problem when it looked like Daredevil wasn't going to be completed in time. The artist was Bill Everett, a man that Stan loved as both a friend and illustrator. Unfortunately, Bill was having some big time health problems. Stan stalled as long as he could but when it became evident they weren't going to have a book, it was King Kirby to the rescue. Stan, Jack and inker Dick Ayers literally put together that first issue of Avengers over a weekend. From concept (Their answer to DC's Justice League) to plot to pencils to script to letterlng to inking to coloring and ready to ship off to the printer, all in the course of about three days. An amazing mind blowing feat. Even more amazing is that issue of Avengers became one of the most important comics Marvel ever published. It's still going to this day. And it kicked off a multi-billion dollar movie franchise.
So yeah my buddy
@AceofKnaves is correct. I really want that Hulk. I'd love to recreate that cover someday.
