In reading some of my JLA Archive editions, I remember being very impressed, as a kid, with the reprinted issue #19. Among other things, it showed the JLAers along with their civilian identities all together on the same striking cover. Moreover, because of unique circumstances, it was also the first time they chose to reveal those carefully guarded identities to each other.
Later, at story’s end, they would all voluntarily agree to forget them, for security and privacy reasons. Superman would perform this task, using an element called Amnesium from his Fortress. Whether this was the first and last time it was ever used, I can’t say. Apparently Q, that information is lost to history. Or is it? In any case, it was awfully convenient at the time.
All of which, naturally got me to wondering, if some similar " reveal " might not have happened with the Justice Society? Or, were they just a lot more trusting, back then?
Stay safe, be well.
