A sort of intriguing "Elseworlds" storyline, with the first two stories in this volume featuring Batman and Superman teamups from 1939 (their first purported meeting) and 1949. The art and story styles are matched to the years the stories are set in. The 1949 story has Superman and Batman both married, and their wives pregnant - although Lois' run-in with Luthor has her exposed to Gold Kryptonite, forever changing her unborn son to a normal human being. Interesting, but Byrne's art is better than his writing. It was rather disconcerting to see Lois and Bruce Wayne both smoking, as fits the times, I suppose. ( )
