If I were a hero, I'd be Martin Luther (Part 2129)...

 Superhero Anydays

Not sure of the artist, but here we have some Earth-2 superheroes...a weird combination of them.  You see, they're mostly Justice Society members...but there's Liberty Belle too, and she never was.  And with the grown up Robin, when he was a member, it was the 1970s, not the 1940s....but Liberty Belle and Mr. Terrific weren't really active at that time.  So....it's just a batch of Earth-2 heroes, like I said previously.

Roughly clockwise from bottom right: The Flash, Liberty Belle, Wildcat, The Atom, Robin, Starman, Black Canary, Dr. Fate, Mr. Terrific and Hawkman

And today we also have a very cute Spider-Man cosplayer.
