Again, you are ignoring Superman's commercial appeal and success in comic books and merchandise in the 1950s. There was no Batmania in the '50s. Batman never outsold Superman in the '50s. And you obviously misunderstood what I meant by Batman's success in the '60s. Sorry I didn't clarify in more detail originally what I meant, but I didn't think I had to be so anal-retentively specific. 1966 and 1967 do make up two years in the decade of the '60s, which Batman comic books did outsell Superman. Again, I didn't say, nor was I intending to claim, that Batman constantly outsold Superman throughout the decade of the '60s.
