Marvel Mystery Comics #12

In "The Search For J. B.", the Angel ventures into a treacherous enchanted marsh to aid Shirley Smith, only to be swallowed by quicksand—until rescued by a towering, enigmatic creature serving a shadowy woman with a deadly secret. With the Piedmont mansion's former owners dead and the Angel and Smith now in peril, the mystery deepens as forces both ancient and sinister stir beneath the surface. Written by Paul Gustavson and illustrated by a then-unknown Jack Kirby (pencils) and Joe Simon (inks), this 1940 issue blends early superhero adventure with gothic suspense, all in a 10-cent comic that stands as a rare early collaboration from the creators who would soon define an era.
