If I were a hero, I'd be Martin Luthor (Part 1230)...

Superhero Anydays

Today we have, by George Perez, the Superman and Batman of Earth-2.

 You can tell they're Earth-2 cause they're older (see Superman's gray hair) and thicker, and their chest emblems are both the original ones from the 40s.

And today we also have some Teen Titans cosplay: Speedy, sidekick of Green Arrow!
