That's the glory of the Multiverse. This simple panel. Some version of the JLA/JSA, all in G.I. uniforms from World War II. I pick it over, trying to see what characters I can identify. I theorize about the fact the women are in traditional superheroic garb, while the men are in uniform. There's a Wonder Woman, a Green Arrow, a Robin, a Star-Spangled Girl (?), a Flash (who appears to be punching out an American G.I.).
For all it's faults, Infinite Crisis finally delivered. This is the feeling I was wanting, the moment of experience that I hoped the series would bring. This small panel is the legacy of Crisis on Infinite Earths. That simple moment where you freeze over a panel, with the immediate though of "what is that? I want to see more of that!"
EDIT: Spandex Justice has the scoop on the women.
