Superhero Anydays

Today we have, by an unknown artist, a lineup of heroeas, mostly, but not all, members of the Justice League Of America.

Clockwise from the front: Batman, Black Canary, Green Arrow, Martian Manhunter, Hawkman, Superman, Wonder Woman, Supergirl (not a JLA member), Green Lantern, Aquaman, The Flash, and Robin (also not a member)

And today we have some more armored than usual Nightwing.
