I worked with a staff member from Tom Kelley Studios back in 1997-1999 before I got into the online adult industry....I helped search online for fraudulent unlicensed reproductions of the Red Velvet Series.
There were also other photos from the series that were never published in Playboy. I own two of these limited editon prints.
