Astonishing Tales #12, June 1972
Man-Thing (Seriously, what kind of drugs to you take to come up with a name like that?) makes his first color comic book appearance in this terrific Ka-Zar story illustrated primarily by John Buscema.
Part of the story was slated to appear in the B&W Savage Tales #2 which did not see the light of day, so it was cleverly re-worked here. Because of the re-mixing, credits on this issue read like an all-star line-up, and include Buscema, Neal Adams, John Romita and Dan Adkins.
Writer Roy Thomas somehow made sense of it all, creating the framing story around Len Wein’s original tale.
Bonus: Man -Thing’s first overall appearance in Savage Tales #1 includes this glorious splash (below) by Gray Morrow.
