Miss Masque began her career in the golden age of comic books appearing in Standard/Nedor's America's Best Comics from issue #23 to the end of the series with issue #31. The Black Terror was the feature story in this title but Miss Masque appeared prominently as the second or third story after the lead one. Quite sexy in her mini-skirted red suit, she was Nedor's answer to Marvel's red dressed Blonde Phantom. The pictures below are all from issue #29, which I believe is her best ever appearance, simply because it is the only story I know of where she is carried after being knocked unconscious. The bad guys are con men who try to defraud rich business men who like to take chances. Miss Masque has a penchant for sticking her nose into other people's business when she suspects foul play. Since she has no super powers, she often risks her own life in the process.
The scenes below are all from one story and show her confronting the con men, battling with them, getting knocked out, carried unconscious to the window of a tall building and tossed out to make it look like suicide. She catches hold of a flagpole and manages to save herself from certain death -- then she returns to bring justice to the bad guys. The carry pic is what makes this story a cut above all her other KO episodes.
