Original post here. This image was researched by Bacchus at ErosBlog as part of the “Γ commission.” The research was originally published at Hedonix as “Γ 033 – X-Ray Love.” Here is what Bacchus found.

The source Tumblr post for this image tags it “Derek Yaniger” which is consistent with the visible “Derek” signature. The artist’s web page is here, and there’s an entertaining bio written in a sort of retro Beatnik jive. This image appears on the artist’s website along with a news item announcing that it was released as a “jumbo sticker” called X-Ray Love. It also appeared in an article about the artist in the Brazilian Playboy.
