Mars Attacks is a science fiction-themed trading card series released in 1962 by Topps. The cards feature artwork by science fiction artists Wally Wood and Norman Saunders. The cards form a story arc, which tells of the invasion of Earth by cruel, hideous Martians under the command of a corrupt Martian government who conceal the fact from the Martian populace that Mars is doomed to explode and, therefore, proposes colonization of Earth to turn it into their new homeworld. The cards depict futuristic battle scenes and bizarre methods of Martian attack, torture and slaughter of humans, as well as various Earth nations being attacked. The story concludes with an expeditionary force of humans volunteering to embark on a counterattack on Mars, in which the Earth force attacks the Martians in their manner. This necessitates the Martians that are still on Mars to defend their homeworld. The Earth attack forces, after destroying the Martian cities and killing the Martians, depart just before Mars is destroyed in the predicted cataclysm, thus ensuring the peace and safety of Earth as the Martian race is seemingly doomed to extinction.
