Featuring an adventure of the Federal Gorilla Bureau! Seriously, this cover seems to be illustrating a story by Alan Hathway called "The Gorilla Speaks", but I have no idea what it's about. Other authors in this issue are Steve Fisher, Paul Ernst, Laurence Donovan, Norman A. Daniels, Ben Conlon, George Allan Moffatt, Jean Francis Webb, and William G. Bogart. If you're keeping score, that's four guys who wrote Doc Savage novels (Hathway, Donovan, Daniels, and Bogart) and another who wrote under the Kenneth Robeson by-line (Ernst, on THE AVENGER), plus the fellow who wrote Pete Rice (Conlon) and one of the many Phantom Detective authors (Webb). Quite a line-up.
