Another classic villain debuts--the infamous Dr.Light!
The story: "The Last Case of the Justice League!" by Gardner Fox, Mike Sekowsky, and Bernard Sachs. Snapper Carr arrives at the JLA Secret Sanctuary only to find a goofball who calls himself "Dr. Light" there, and he tells Snapper the tale he likes to call "The Last Case of the Justice League!"
Dr.Light uses his Disco Ball of Doom to send JLAers to other worlds--Aquaman to an all-desert planet, Manhunter to an all-fire planet, etc. Luckily, Superman and Batman senses something was up before they were transported, and switched identities, which helps them escape and then rescue the other JLAers.
Roll Call: Superman, Batman Wonder Woman, Aquaman, Flash, Green Lantern, Martian Manhunter, Green Arrow
Notable Moments: Another longtime villain makes his first appearance--Gardner Fox was on a Stan Lee-esque run here, where with each issue he was creating a new bad guy that would go on to have a long run as a DC villain.
There's a letter by a Paul Gambaccini, who later became a famous radio and TV commentator and music producer in the UK. He never lost his love of comics though, and was tapped to write the intro to The Justice League of America Archives Vol.1.
