Interesting and hard to find pulp fiction edition of The Hot Summer Days by Sue Kaufman. Judging from the back cover description this was a racy novel about couples who "swing" way back before that was even a thing! It's missing the first few pages, including the copyright page, it starts on page 7. I was able to date it to 1960 which is when the version of the Ingrid Bergman book shown at the end was published.

It's in fair vintage condition overall with signs of wear and age including yellowing to the paper and a pen mark on the cover. Still very readable and collectable edition.

This item is sold from a vintage boutique in Pendleton, South Carolina.
