The World's Greatest Super-Heroes is the name to the oversized slipcased hardcover collection, consisting of six oversized graphic novels all done by writer Paul Dini and artist Alex Ross. The graphic novels are; Superman: Peace on Earth, Batman: War on Crime, Shazam!: Power of Hope, Wonder Woman: Spirit of Truth, JLA: Secret Origins, and JLA: Liberty and Justice. The artwork is of Ross' very own photorealism, and the books themselves were created after the success of Ross' and writer Mark Waid's famous Kingdom Come.
