Supernatural Thrillers

It - The Thing that Couldn’t Die first appeared in Supernatural Thrillers Issue 1. Based on a short novelette by Theodore Sturgeon, which was originally published in 1948, “It” is obviously the basis for Man-Thing, Swamp Thing, and just about every other muck monster, although all of the above can be seen as offshoots of two other comic book creatures that pre-dated Sturgeon’s novel: The Heap, which first appeared in Air Fighters Comics 3 and Solomon Grundy in All-American Comics 61.
