The eighth JLA/JSA team up, and the first time the world met Golden Age Batman.
Check out the top panel, where they explain how all these “old” dudes are still young. I don’t think this time-change concept was continued for very long, but kudos to Denny O’Neil for thinking it up.
Incidentally, back in issue #78, he also started the Black Canary/Green Arrow romance.
So, the human inhabitants of the late Earth-Two enjoyed an average lifespan that were twenty years longer than those of Earth-One, eh-?? That sounds like pure bad comic-book drivel to me! Why would the average lifespans on any other Earth besides Earth-One be any longer than the lifespans of any other Planet Earth-?? There is simply no logical basis for this. I am with the majority mindset that the JLA of Earth-One is more interesting than their JSA predecessors, both esthetically, and otherwise. Sleeker in appearance, certainly more sophisticated in aspect, and with overall more interesting adversaries, however, I just wish that we could have the Legion of Doom in their comics about forty years sooner. A hero is defined by his adversary/adversaries, and comic-book super-villains just don’t get more adversarial than the Legion of Doom! ( their Marvel analogs, the Masters of Evil, are pretty nasty, though ) Interestingly, Mr. Ekko touches on 1969’s ‘Justice League of America’ #78, which is noteworthy for three major reasons: 1) The JLA leaves their ( rather low-tech ) cave headquarters for their awesome, nifty-keeno space satellite “22,300 miles ABOVE the city of Metropolis, in perfect geo-synchronous orbit, ABOVE the Planet Earth…………” 2) The first appearance of the more-than-slightly-subversive ‘May-December’ Green Arrow/Black Canary romance, which continues to give hope to old perverts everywhere! ( I hesitate to say “like me!” ) and, 3) It was my own very first issue of ‘Justice League of America’! Imagine my astonishment at picking up this issue with absolutely NO prior exposure to the JLA, and witnessing the Green Arrow accidentally setting a river on fire, the “right guys”, as Ollie put it, showing up to handle the matter, ( in a sequence which was adapted nine years later onto the episode of ‘Challenge of the Superfriends’ titled “Trial of the Superfriends” ) and getting to join the League “beaming up” to their awesome, bitchin’ new space satellite headquarters ( as seen through the eyes of super-cynic Green Arrow ) and wondering why is this old pervo with the bow and arrows harassing this poor, little pretty lady in the pretty stockings-?? As I say- an epochal issue! That’s the thinking man’s way of saying: “A lot happened in that issue!” As it should have, inasmuch as it was my very own initial exposure to the awesome Justice League of America! And that’s the truth!
