According to the Drake’s Way tumblr, this is an advertisement that appeared in Horror Sex Tales #1, advertising Monster Sex Tales #1 “by” infamous director and author Ed Wood Jr. According to this forum post, Wood wrote at least three of the stories appearing in Monster Sex Tales #1; another site claims that Horror Sex Tales #1 was also “apparently written and edited entirely by Ed.” (An article at BadMags credits him with work for both publications, but also goes into detail about the difficulties with attributing Wood’s prolific magazine writing.) Both magazines were published by Gallery Press in 1972. This site claims that two stories in Monster Sex Tales were “partly cannibalized from The Adult Version of Frankenstein by Hal Kantor”, which may explain the theme of the advertisement art. However, The Adult Version Of Frankenstein appears to have been an adult novelistic treatment, not described in catalogs as having associated artwork. No information could be discovered about the magazine artist who drew the advertisement.

The advertising copy reads:

“Frankenstein, Raging Sex Monster! See the famous Frankenstein monster rage a lust-frenzied path across the pages of the most shockingly strange magazine to come to you in ages!! MONSTER SEX TALES!! A startling collection of tales about the half-man/half creature of book and movie fame — exciting and diverse interpretations by astute writers of today — guaranteed to keep you pinned solidly to your chair as you read from cover to cover!!
