Used paperback in Very Good condition. "Holy Moley! It's the Man of Steel against the World's Mightiest Mortal! One is the super-powered sole survivor of an advanced alien race. The other is an ordinary teenager whose ancient mystical powers manifest when he shouts the magical word "Shazam!" Both have super-strength, flight, invulnerability and super-speed. But who is the mightiest--The Big Blue Boy Scout of The Big Red Cheese? And what would make two such noble heroes come to blows? But the heroes aren't the only ones joining forces. What sort of havoc can be wrought when Mr. Mxyzptlk and Mr. Mind hatch their plans together? Or when Black Adam and Quarrmer (a.k.a. Sand Superman) star impersonating Superman and Shazam? See the two titans battle their greatest enemies as well as each other (with help from Supergirl and Mary Marvel) in this timeless crossover collection!"--Page 4 of cover.
