Superman not cool? The comic that gave us Supergirl, the Legion of Super-Heroes, Krypto the Super-dog, Beppo the Super-monkey, the Superman Revenge Squad, umpteen types of Kryptonite, Jimmy Olsen and the Carrot-Top Cut Ups, the bottle city of Kandor, etc., etc. not cool? The Mort Weisinger-edited Superman comics of the '50's & '60's are some of the best fun to be had in four colors!
And don't forget Mort's finest moment....BIZARRO!
