This story is from Adventure Comics #115 (April 1947); originally published by DC Comics (at that time known as National). "The Adventure of Jaguar Boy" was written by Don Cameron and drawn & inked by John Sikela.
I've sat on this one for quite a while since the scans aren't very clear, but posting an actual golden age superhero yarn that still fits within the "jungle-theme" motif of the bulk of the Catacombs stories is a rare treat.
The Catacombs is grateful to Don "Zu-Gogo" Falkos for providing the scans for this story. Note: The copyright for this issue, its contents and artwork belong to the original publisher and/or creators and is reproduced here solely for entertainment purposes.
