If I were a hero, I'd be Martin Luther (Part 2304)....

 Superhero Anydays

Today we have, by an unknown artist (although it looks like Mike Parobec), and it looks like it an amalgamation of possibly four separate comic book covers.  It's a bunch of JSA members.

Left to right: Green Lantern, Wildcat, The Flash, with Johnny Thunder's Thunderbolt behind them, Dr. Mid-Nite, Hawkman, Hourman, Sandman, Dr. Fate, The Atom, Black Canary, Starman, Mr. Terrific and Johnny Thunder with the Spectre behind them.
