Regarding the credits: Bob Burns, next to Forry Ackerman, is one of the foremost collectors of fantasy movie memorabilia. He often played a gorilla in comedies and television shows. Paul Blaisdell designed monster costumes and props for many AIP and Corman film productions in the Fifties. This was their attempt to do a monster magazine that was a little more scholarly than Famous Monsters. The magazine did well until a fire destroyed their production facilities.
