If I were a hero, I'd be Martin Luther (Part 4077)....

 Superhero Anydays

Don't know what this is from but it shows the five Earths that were supposed to remain after the Crisis On Infinite Earths.

Earth-S, home of the Shazam family. 

    showing: Captain Marvel, Captain Marvel Jr and Mary Marvel

Earth-X, where the Nazis won World War II and was home to the Freedom Fighters. 

    showing: Phantom Lady, Human Bomb, Uncle Sam, Firebrand, Black Condor, with Doll Man and            The Ray in the air.

Earth-4, home of the heroes from the Carlton Universe

    showing: Sarge Steel, Judomaster, Blue Beetle, Peter Cannon and Question

        in the air: Nightshade, Peacemaker, Captain Atom

Below we have Earth-1 and Earth-2 somewhat merged.

    showing: Superman and Lois Lane of Earth 1, Wonder Woman from both Earths, and then Lois Land         and Superman of Earth-2, who married.

    Above them: Wonder Girl, Batgirl, Supergirl, Robin, Batman of Earth-1, then the ghost of Batman of 

        Earth-2 (as he was dead), Robin, Power Girl, Huntress and Fury (all roughly counterparts of the             Earth-1 heroes).
