Miss Masque appeared in 9 issues of America's Best Comic, usually as the back up story to Black Terror who was Standard/Nedor's top superhero. In this issue she attends a high society ball and stumbles on to a plot to steal highly valuable jewels from the ladies in attendance. She follows one of the theives to their hideaway, encounters them, and is overpowered, carried away, and put in bondage. Always resourceful she manages to kick her way out of danger, get loose from her bonds and defeat the jewel theives. We do not see her KO'd or even manhandled, but she does appear to be unconscious in the carry scene, which is low grade due to its small rendering (even though it comes close to being a full body shot, it is way too small to fully satisfy). Miss Masque was Standard/Nedor's attempt to provide a superhero to compete with Marvel's Blonde Phantom: i.e., she wears a red costume, has blonde hair and great legs, and no superpowers (making her vulnerable and often easily overpowered). The art here could have been, and would have been much better if the KO had been shown, and if the carry scene had been rendered much larger.
