Despite the racy look of it, 1,2,3… Swap! is one of author Curt Aldrich’s tamer efforts. Writing from the mid-60s and into the 80s, he specialized in swapping fiction, giving us many memorable books, including Cock ‘o the Swap, Swap Epidemic, and Swap ’69. Not one to limit himself, Aldrich also went fully hardcore with rather shocking titles like Daughter Loves Horses, Spread Big Sister, and Horny Holy Roller Family.

It could be Aldrich showed such range because he was actually a pseudonym used by various authors, including Richard Curtis, who later became a literary agent. Many of these books featured low-rent cover illustrations that were little more than sketches, but this psychedelic effort by an unknown artist (looks like it could be Robert Bonfils, but absent confirmation, we'll go with unknown) is first rate. We'll be posting more Adrich books in the future.

Update: turns out the art is by Darrel Millsap, who illustrated scores of covers for Greenleaf Classics. It only took four years to clear that up, but better late than never.
