In honor of the World Series and all the unintentionally sexual terminology you hear on sports broadcasts—and he manages to squirt that one up the middle!—we thought we’d share this cover for Kozy Books’ sleaze novel Squeeze Play. It was written by Walter Feldspar, whose name is a pseudonym of course, but we don’t know who occupied it. Orrie Hitt is a prime suspect though. Whoever it was, we have to give credit for cleverness—feldspar is a mineral that has no value but makes up the majority of earthly rock. He’s doubtless saying the same about his fiction—no value, but can be found everywhere.

Given enough time anything can accumulate value, though, and such is the case with ’60s sleaze fiction. Kozy output seems more popular all the time, so in acknowledgment of that fact we have a selection of their covers below. You would not necessarily call these pieces completely successful, with their often unreadable yellow-on-white or orange-on-orange text, but in terms of promoting the product the covers told you exactly what you were going to get. The company had a habit of not crediting art, so we’ve nothing for you there. But enjoy the selection anyway, and if you want to see a real Kozy winner, check here.
