In 1972, Justice League of America (vol. 1) celebrated its 100th issue by doing something different for its annual meeting with the Justice Society of America of Earth-2. Instead of a two-issue story-arc, they expanded the story to cover three issues (100-102).
Of course, it would not be the seventies without a little bit of sexism. Yet I ask you what is wrong with Green Lantern referring to Diana Prince’s arm as “pretty” or Black Canary making a reference to men and their stomachs. Now days this sort of patter in a comic book would result in near deadly acts of violence as the characters try and make a point.
The three issues were jam-packed with all sorts of exciting adventures such as this sequence where Circe turned Zatanna into a hummingbird. Actually, it was Speedy, under a spell of Circe, who shot Zatanna with an arrow.
Thirty-five super heroes, including Diana Prince, were on hand for the celebratory issues. Although they were not doing much in the way celebration as they were too busy trying to save the universe that Earth-2 resides in.
Here is a group picture from issue #102 of not all of those who appeared in the series. Where there is overlap between the two Earths, I have noted it.
Starting with the back-row and left to right:
Green Arrow (earth-2), Elongated Man, Wildcat, Dr. Fate, Stripsey, Shining Knight, Hawkman (earth-1), Dr. Mid-Nite, Crimson Avenger, Hourman, Sandman, Starman, Metamorpho.
Middle Row (All from Earth-1):
Green Arrow, Green Lantern, Atom, Superman, Batman, Red Tornado, Flash
Wonder Woman (Earth-2), Stripesy, Black Canary, Speedy (Earth-1), Johnny Thunder, Zatanna, Aquaman, Vigilante.
There are a some who are missing from the group picture and one notable person present for the three-issue celebration, was Diana Prince (aka Wonder Woman). During a brief period in the early seventies when the Silver Age of Comics was sliding into the Bronze Age, Wonder Woman had lost her superpowers and she became known only as Diana Prince. Yet although she had lost her superpowers that did not mean she was still not a force to be reckoned with. Not to give anything away, but here she is whacking off the bad guy. (Correction: whacking off the bad guy’s hand.)
The series even comes with a montage where everyone comes together to work towards the solution.
The issue in which Wonder Woman lost her super powers was WW issue #179, December 1968.
