>>97236344That's the Golden Age Superman.
If I'm not mistaken, it goes like this:
1940s: Kal-L, member of the JSA, declared to be from Earth 2 in the sixties.
1950s-1985: Kal-El, Classic/Silver and Bronze Age Superman, member of the JLA, was a Super Dick on occasion, teamed-up with Kal-L now and then.
1985-2011: Kal-El, Post-Crisis Superman, the one most of us know.
2011-2016: Kal-El, New 52 Superman, younger. Got merged with Post-Crisis Superman into the current version.
Kal-L died in Infinite Crisis, right? What happened to Pre-Crisis Superman?
