The photo, shared online by Reddit user UnknownJ25, appears to have been taken in one of Warner Bros.' Burbank offices. Along with already announced and/or airing series like "Mike Tyson Mysteries" and "Be Cool Scooby-Doo!" is a poster for what appears to be an as-yet unannounced "JLA" show.
Pictured on the poster, in silhouette, are a number of DC heroes, including Superman, Wonder Woman, Batman, Firestorm, Hawkgirl and Shazam, among others.
While the poster could be for the classic Paul Dini/Bruce Timm series, that seems unlikely considering that the rest of the posters are for current series.
CBR News has reached out to Warner Bros. for confirmation.
