The JLA Uses Trading Cards, the JSA Audition Pictures
"The JLA Uses Trading Cards, the JSA Audition Pictures" from Justice Society of America vol.3 #1 (DC, 2007) by Geoff Johns, Dale Eaglesham and Art Thibert
At a time when the JLA writer was fetishizing and cannibalizing the team's Satellite era, JSA was doing the same with Kingdom Come. I guess that was the hook that would make the JSA relevant to newer fans. So we got Earth-2 Superman and Magog and Alex Ross covers and some of the JSA legacy characters created for Kingdom Come too. Hey, if it can keep the Golden Age heroes in the public eye and heart!
