The Phantom Lady

Joining the ever growing list of comic book characters previously unknown to me is the Phantom Lady.  Golden Age Comic Book Stories posted several covers and one complete story from this comic in the late 1940's.  According to Wikipedia, Sandra Knight, the daughter of a U.S. Senator, was the Phantom Lady, who

used a "black light projector," a device which allowed her to blind her enemies and make herself invisible. She drove a car whose headlights also projected black light when necessary. She was sometimes assisted by her fiance, Donald Borden, an agent of the U.S. State Department.
