THE STORY:

THE WAIT IS OVER! The most eagerly anticipated comic book crossover of all time has finally arrived, with alternating Prestige Format issues by Marvel & DC Comics! What cataclysmic threat could endanger two universes - and dwarf the combined power of both Earth's Mightiest Heroes and the World's Greatest Super-Heroes?

The world finally learned the answer in September 2003!

This is good old-fashioned super-hero crossover stuff, in the vein of Crisis on Infinite Earths or Secret Wars, back when the events themselves were cool and fun reading.
