2001: A Space Odyssey (Treasury-sized)

2001 Treasury on Ebay
2001 A Space Odyssey Treasury Edition One issue, 1976.

This was a one-off comic done in the same size and format as Marvel's mid-70's Treasury editions, to take advantage of the fact that Marvel had gotten hold of the license to do a comic book based on director Stanley Kubrick's film of the same title. (Which was odd, considering the film had come out in 1968.) Jack Kirby, having returned to Marvel after his stint at DC Comics, wrote and drew the entire thing himself, basing it rather loosely on the film.
