My original tumblr post was here. This image was researched by Bacchus at ErosBlog as part of the “Δ commission.” The research was originally published at Hedonix as “Δ 049 Robot Gangbang.” Here is what Bacchus found.

This image appeared on page 11 of Penthouse Comix 9 (September/October 1995) as part of that magazine’s second annual Damsels In Danger Spectacular. It may be seen to be titled “Iris Dewey, Lady Lawyer” and signed “Johnson 95”.

According to ComicBookDB, the “Johnson” signature corresponds with Dave Johnson, aka ‘Reverend Dave’ and/or Cornelius, whose credits include “Penthouse Comix #9 – ‘2nd Annual Damsels in Danger Issue’. His defunct-since-2009 website may be seen in the Internet Archive, and he maintains a presence on DeviantArt. ComicsVine lists him as a prolific artist with 795 artist credits.

In confirmation of this attribution, the previous page in Penthouse Comix 9 contained the following image, which shows a fragment of the same artist’s signature lower right and is captioned “Cybersex by Dave Johnson”:

For a comic book artist so prolific, it’s curious how little biographical information seems to be available on the web. His Blogger profile lists six (!) different blogs he maintains or has maintained, along with this self-description: “Just a cover artist/animator commenting on what he thinks are good and bad cover designs. Oh yeah, he’s a multi-Eisner and Harvey award best cover artist nominee and even won once.”
