Here is the classic introduction & origin of Jann of the Jungle (aka Jane Hastings) from Jungle Tales #1 (Marvel/Atlas; Sept. 1954). "Rampage!" was written by Don Rico and illustrated by Art Petty, but this story was reprinted in Jungle Action #3 (Feb. 1973); which is the source of these scans. The cool bonus cover is by Jim Starlin and Frank Giacoia.
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.
