Limited edition, hand numbered poster by Phantom City Creative for the Alamo Drafthouse.
Club magazine featured several collectable centerfold posters during the 1980s, including this one from 1982.
This unusual double-sided poster was used to promote the 8MM film of Insatiable. Five scenes were sold separately, because money. It's not clear where this poster would have been displayed (adult bookstores? your uncle's basement?) or if it was given as a promo gift at a consumer electronic show.
