World’s Finest

   Superman and Batman have been linked to each other since 1941. They first appeared in the same comic book, All-Star Comics (1940) seven in 1941.

   They had shared covers on World’s Fair Comics and World’s Finest, but All-Star issue seven paired them on a mission with the Justice Society to raise $1 million dollars for war orphans. However, they would not share the same panel.

   It wasn’t for another 11 years that DC’s big two would meet – for the first time.

Superman (1939) 72

  It would take an over-booked cruise ship to pair Superman and Batman. Superman (1939) 76 thrust Clark Kent and Bruce Wayne together as they shared a room on an ocean liner. When a tanker exploded near their cruise ship, they were each found out in the moon light’s shine through the portal in their room.

   They would promise to keep each other’s secret as the teamed to help with the disaster.

   History would be repeated when DC kicked off their New 52. This time in Justice League (2011) one.

   In other media, Batman and Superman met at different times and for different reasons.

   They would join forces even before their comic book encounters during the Adventures of Superman radio serial story arc Mystery of the Wax Men in 1945.

   Another first would be for the Superman: The Animated Series two-parter World’s Finest. Together they thwarted Lex Luthor and the Joker.

   Yes, they did meet on the big screen, but the less said about that, the better.
It would be interesting to know when these costumes were paired for sale allowing kids to have their own World’s Finest adventures.
