I have just listed several vintage sleaze paperbacks as well as some bondage and fetish material (all auctions). See my other listings. Happy to combine shipping on multiple purchases. 

Elliott, Dan. Sex Machine. [San Diego]: Rapture Novel, No date [1967]. First Edition. PBO. 206 (not in Holroyd). Cover art by Doug Weaver. A few small indentations to front cover, otherwise a near fine copy. Scarce. "It cost him only ten dollars, a 70-minute jet flight to Japan, two electrodes fixed at his temples, and a special gadget called a Receptor ... and Ron Larson became Blackbeard!" Bad things happen after this.
