Elseworlds: Superman, Vol. 1

"In Elseworlds, heroes are taken from their usual settings and put into strange times and places - some that have existed, and others that can't, couldn't or shouldn't exist. The result is stories that make characters who are as familiar as yesterday seem as fresh as tomorrow. Featuring Superman as the Dark Knight, Kal-El raised in medieval times, Superman as the sole survivor of a nuclear Armageddon, Private Atticus Kent as an abolitionist superhero in the American Civil War, Superman the greatest athlete on Earth and Golden Age Superman at war with Mars!"--Back cover.
