30 Day Challenge Question 22: Favourite dimension
Straght away this was Earth 2.
DC’s multiverse was often used as a way to tell alternate stories as well as preserve IP. Before 1985’s Crisis on Infinite Earths these worlds kept characters that DC used in the past as well as others that they had acquired. Earth-X was Quality Comics characters, Earth-S was Fawcett Comics and Earth-4 was Charlton Comics, but before all that there was Earth-2. Earth 2 was the home of the Justice Society of America (the first ever Superhero Team), the stand-in for the Golden Age Superman as well as ancillary teams the All-Star Squadron and Infinity Inc.
I wrote about my fondness for this concept here.
