Justice League of America #29

DREW:

I grew up reading my dad's Silver Age collection, and this book was among them. It's one of my favorites. This introduced the alternate world known as Earth-3, where every superbeing was a criminal and history was a warped reflection of real events: Columbus was an American who discovered Europe, England won its independence from the United States in 1776, Abe Lincoln was an actor who shot President John Wiles Booth, and so on. Instead of a Justice League of America, this world has the Crime Syndicate of America. The CSA comes to our world (Earth-1), beats up the JLA, and then it's up to the Justice Society of America (from Earth -2, of course) to save the day.

Dudes, DC Silver Age stories don't get ANY better than this.
