Swap Circuit was written by Thomas P. Ramirez in the guise of Tony Calvano, with cover work by Darrel Millsap, and published in 1968. A couple set up swapping sessions for profit only to see their scheme go awry when they attend an orgy that’s out of their league. This piece of art caught our eye because it fits perfectly into our large collection of swapping covers, which you can see here. Don’t trade it for anything.
It floats? How weird. I would have thought something that size drags you down like an anchor.
