Published by Fiction House, Jungle Stories ran from 1938 to 1950, for a total of 59 issues. Judging from the covers below (and, of course, the title of the magazine), Jungle Stories dealt with the adventurous of life in the jungle. It appears that several issues featured the adventures of Ki-Gor, the lord of the jungle. I haven’t read any of them but I’m sure Ki-Gor was probably a totally original creation and had nothing in common with Tarzan. There’s probably a world of difference between being the king of the jungle and being the lord of the jungle.
