Years ago when I was working customer service, a friend--Steve Baker--had bought this paperback used. He described its publishing history as that of a group of books that were naively titillating (like "racy" photos from the 1920s) and printed without copyright or publisher information. The first page was the first page. The story was the most hilarious thing I had every read. It exists with only one hit on Google as a bare-bones entry at Amazon.com.
One hit, that is, until now.
