Alex Ross's dramatic artwork appears on the cover of Superman/Fantastic Four, a Marvel/DC collaboration that uses the "Treasury Size" typical of the earlier crossover comics. Unlike those comic books, which depict DC and Marvel superheroes sharing a common world, this story uses the current notion that the DC and Marvel Universes co-exist in alternate universes. The story has the characters investigating the possibility that Galactus devoured Krypton, a notion which has been kicked around the Web here and there.
