Superman becomes the pawn of ultra-dimensional forces on the eve of the Final Crisis. He must recruit the Supermen of five worlds to battle an epic, reality-spanning menace that originated during the Crisis on Infinite Earths!  Join the Man of Steel and his alternate-earth counterparts for a mind-blowing voyage to the edge of the DC Universe - and beyond! Can these super champions overcome their differences and save all existence from extinction? When Mandrakk the dark Monitor awakens, can Superman prevail against the ultimate enemy of life and find his way home before utter darkness falls across the cosmos? Twists and turns that must be seen to be believed and cosmic action on a mind-shattering scale!

Key books; first cameo appearance of Superdemon, Etrigan from an alternate Earth, first full appearance of Mandrakk, the Dark Monitor. Both books include a unique 3-D section with eye-popping visuals and a pair of 3-D glasses.  Very fine condition.
