Superman was an honorary member of the Justice Society of America during the Golden Age of comics. In the annual Justice League/Justice Society crossover stories of the Silver Age, the Superman of Earth-2 began participating in JSA adventures on a more regular basis. Since "Infinite Crisis", members of the JSA have regained their memories of the Golden Age version of Superman. In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Superman was not a member of this team.
