1964 Cover of The Scandal Set

This is the cover of the 1964 Signal Sixty book The Scandal Set by Jason Morgan. I got this from Joe Jusko, but it isn't by him alas. The artist is unknown. This is used on both the front and the back, flipped and made dark monochrome green. The cover cuts the image just past the hint of nipple and right at her crotch. The hint of nipple is still visible front and back. This is billed as "A behind-the-scenes glimpse of suburban sin-often whispered about but seldom pinpointed," hot stuff for 1964.
