Marvel did a reprint of good old X-Men #1, but with the four separate covers as one complete wrap-around. It’s been re-colored as well, and on high-quality paper. The inside cover (pictured here) is a second poster, and Jim Lee drew a number of additional two-page spreads for the interior. The coolest one is the one with all the villains.
