Consider this an engraved invitation to a spectacular anniversary celebration, as writer Paul Levitz brings the World’s Finest face-to-face with the Legion of Super-Heroes. Lex Luthor has unleashed a threat so powerful it’s garnered the Legion’s attention in the distant future. But they can’t take him down without a trip to the past to recruit Batman and Superboy. And there’s more – Joe Kelly and an A-list roster of writers and artists chronicle the history of the Man of Steel and Dark Knight in stories that jump from yesterday to the distant future. Adam Hughes writes and draws a tale starring Supergirl and Batgirl, J.T. Krul and Francis Manipul deliver a tale of Superboy and Red Robin seeking advice from their mentors, Ace and Krypto get leashed by Duncan Rouleau, David Finch writes and illustrates a story for the first time, and Joe Kelly, Steven T. Seagle, Billy Tucci and many more surprises help commemorate this anniversary extravaganza. Here’s a look at the first story. SUPERMAN/BATMAN #75 hits 8/25.
