Trapped on Earth Prime, Adam Strange desperately seeks the Justice League of America in order to prevent an alien menace from destroying the planet. Unfortunately for him, the Justice League are only fictional comic book characters and everyone thinks Adam is crazy. So what’ll his next step be? A trip to the DC Comics offices, of course. Meanwhile, Kanjar Ro wreaks havoc on Earth 1, and Wonder Woman, Green Arrow and The Flash will have to venture to Earth Prime to save Adam Strange in order to restore his memory of who he really is. This new story is by Cary Bates, Gordon Purcell, Jose Marzan Jr. and Andy Smith. DC RETROACTIVE: JUSTICE LEAGUE OF AMERICA – THE ‘70s also features a classic tale from the ‘70s by Cary Bates, Elliot S. Maggin, Dick Dillin and Frank McLaughlin, and arrives in stores on Wednesday.
