Jungle Jo makes his Catacombs debut in a tale entitled "The Evil Eyes of Death" from Terrors of the Jungle #21 (Feb. 1953); originally published by Star Publications, although this was a reprint from an earlier 1950 Fox series.
Jungle Jo is rather lame, all things considered, and the GCD doesn't even list any creator credits for this story. Maybe they feel the same way? The Catacombs is grateful to Don "Zu-Gogo" Falkos for providing the scans for this story.
