ANAHEIM, Calif.—The Wondercon convention is taking place now in Orange County, to the delight of comic and sci-fi nerds throughout the southland. The event takes place April 18-20 at the Anaheim Convention Center, and among the attractions are two familiar names in adult entertainment: Tera Patrick and Anastasia Pierce.

The two adult stars will be on the scene at Wondercon to sign a limited-edition poster as well as books created by pin-up artist Lorenzo Sperlonga, who has created a special art piece for this occasion. This is the first time Tera Patrick and Anastasia Pierce have been portrayed together.

The artist will host both stars in his exhibit space, Booth # 672, for the entire weekend. This exclusive limited-edition poster will be signed for fans and collectors at the event. Tera and Anastasia have previously posed for Sperlonga and graced the covers of his books Poison Apples and Steampunk Dolls and Femmes Fatales, both published by Heavy Metal.

Guests are invited to meet the models and artist for signatures and photos.
