Originally credited to Manny Stallman? this way : "Unsigned but the art resembles the previous signed story. Art credited to Stephen Kirkel in index of reprint."
The artwork is neither of these. It is Henry Kiefer, and that is very clear when looking at the faces with broad mouth and marked lower lips, and the squinting eyes. None of his figures ever focused their eyes, and none made faces more ugly. That is the best clue to Kiefer. He worked on many Classics Illustrated: Twenty Thousand Leagues Under the Sea, to mention only one. Art ID by Steinar Ådland December 2010.
