It's been at least 3 years since I've made any serious effort to organize recent card purchases. Consequently, I've got piles of cards everywhere. While I'm putting stuff away I'll be making posts about some of the cards I'm handling.
Circa was a short-lived set released by Fleer/Skybox in 1996 through 1998. In 1998 it was renamed Circa Thunder. In 1999, Skybox released Skybox Thunder, maybe a descendant of Circa Thunder, who knows. Circa's design is very much in keeping with the odd, almost surreal designs that Fleer put out in the late 1990s.
