It has been more than fifty years since the publication of the first line of Topps’ Mars Attacks trading cards and the nationwide moral outrage over the cards’ graphic violence and implied sexuality that ensued. Kids thrilled to the gory images and monstrous Martian invaders, but parents and authority figures had a hairy fit. Topps attempted damage control by reissuing the cards with repainted art to take out the offending material, but the company ultimately suspended the line following inquiries from a Connecticut district attorney. The original cards became collector’s items.

In the years that followed, Topps turned Mars Attacks into a franchise of comic books and action figures and last year celebrated the 50th anniversary of the original line by reissuing the cards in an expanded set called Mars Attacks Heritage. Now, the company is bringing the controversial sci-fi card set back in grand style with the release of Mars Attacks: Invasion, the first story-based line since the original hit stores in 1962.
