B:TB&tB season 2 episode 5 "The Golden Age of Justice!" Directed by Michael Chang.
Well this a change of pace for B:TB&tB's usual color palette, huh? In this episode we go back to the days of the Justice Society of America in WWII (back before color was invented). Notice that the JSA logo is a subtle nod to the old DC comics logo.
