The Maiden of Might! A Birthday Tribute to Supergirl
On March 31 1959, Supergirl made her debut in the pages of Action Comics #252. There were precursors to the character – the most famous was Super-Girl, created by occasional audience proxy Jimmy Olsen in 1958 thanks to a wish and a magic totem --- but it was the strong response to that story that persuaded series writer Otto Binder and artist Al Plastino to create Supergirl for real, as a permanent addition to Superman’s supporting cast.
