Nice, but not accurate. Superman and Batman weren't part of the original Justice Society, except as honorary members. Johnny Thunder joined the team long before either of them did; heck, he joined before Wonder Woman did, and she was one of the first to join the team. The roster also doesn't show the Spectre, Sandman, or Atom, all of whom were also founding members. I'll forgive them for showing Wonder Woman and Dr. Mid-Nite; because while they weren't founding members, it didn't take long for them to join.
In the other hand, there's nothing about Hourman, Starman, Mr. Terrific, Wildcat, or Black Canary, all of whom joined the team during the Golden Age. They all have at least as much justification to be there as Superman and Batman, and arguably more justification.
