ArtInfo spotlights a satirical poster campaign by Oakland artist Neil Rivas that uses superhero illustrations by the likes of Jack Kirby, Alex Ross, Jae Lee and John Byrne (completed with trademarked logos) to address the hot-button political issue of illegal immigration. Titled simply "Illegal Superheroes," the posters feature such characters as Wolverine, Superman, Black Widow, Wonder Woman and Optimus Prime, whose presence in the United States would likely violate federal law.

Purporting to be from U.S. Immigration and Customs Enforcement, the posters caution, "Super heroes who enter this country without proper authorization are breaking the law, plain and simple. These ‘illegal super heroes’ are subject to deportation at any time. Their very presence is in direct violation of federal law.” The customized hotline numbers at the bottom of each flyer provides the caller with details about each of the undocumented heroes (for instance, "The ThunderCats, a family of cat-like humanoid aliens from the planet Thundera, are known to have entered the U.S. illegally when they saved the world with Superman from Mumm-Ra and his Mutants in a 2004 DC crossover"). ArtInfo has the full breakdown of the messages explaining each character's illegal status.
