The art in question was produced between the years 2004 and 2007. The images were sourced from old issues of National Geographic and a European naturalist magazine that were legally sold over the counter in a used bookstore in Salt Lake City, UT. Gazelam themself is a naturalist (nudist). The art was never promoted in connection with the Sunstone session to my knowledge, and it was not going to appear at the session.
After looking at GA's site, the above does not surprise me at all. Thanks for the confirmation of what common sense was telling me.
