Jan of the Jungle by Otis Kline 1931 Ace Book F-400.

Book is in good condition I have included picture of any and all damage.

A rousing jungle adventure of revenge, lost worlds, wars and romance.

Raised in a lab (alongside a chimp) by a brilliant, but misguided scientist, a young boy is trained to be a killing machine. But the young boy, Jan, is clever enough to escape from the lab and make it out into the surrounding swamp with his chimp mentor at his side.

The swamplands offer Jan has his first taste of freedom. He grows up fast, and has several run-ins with the wildlife of the swamps--crocodiles, snakes, bears, etc..

He soon discovers a lost world, a Lemurian princess and adventure beyond his wildest dreams...

Full of intrigue and adventure, this classic is a must for adventure-pulp literature fans!
