Greenleaf Classics had the most ridiculous covers of any mid-century publishing company. There’s no contest. This one for Clyde Allison’s The Sex Spree is both absurd and, thanks to its colors, beautiful. Unfortunately the art is uncredited. The book appeared in 1962 from Greenleaf’s imprint Midnight Reader, with author William Knoles the man operating behind the Allison pseudonym. Many Greenleaf pen names were shared, but as far as we can tell Allison belonged to Knoles alone, and he used it to write Greenleaf’s spy-themed Agent 0008 entries, which are among the company’s most collectible books. We’re going to get to those in a bit.
