The Atom joins the Justice League!
The story: "The Menace of the 'Atom' Bomb!" by Gardner Fox, Mike Sekowsky, and Bernard Sachs. The JLA decides to vote in a new member("Adam Strange!" cries The Flash), and as soon as they vote in the Atom, all of them realize they have no idea who that is!
The JLA head to Ivy Town to investigate, but on the way they release they're starting to forget who they themselves are! Turns out its the work of the mysterious Mister Memory and his "De-Memorizor"!
Roll Call: Superman, Batman Wonder Woman, Aquaman, Flash, Green Lantern, Martian Manhunter, Green Arrow, and new member The Atom!
Notable Moments: Mister Memory is actually Professor Amos Fortune in disguise, a nice callback to a previous issue when that was still pretty rare in comics.
There's a sweet moment at the end, when the JLA shows The Atom his chair, and he sees that its sitting on the floor! But the Atom is too good-natured to say anything, so he decides not to complain, only for the JLA to show him the chair has the abillity to hover in the air, so he can fully participate in JLA meetings! Again, what kid wouldn't want to hang out with these people?
This issue doesn't feature the typical new-member title-page scroll, one of my favorite touches. Oh well, maybe for Hawkman...
