Lady Luck appeared in Smash Comics from issue #42 to #89, a run of nearly 50 issues in all. Also of considerable noteworthiness, she had a color comic strip in the Sunday papers of 20 major cities from 1940 to 1946. She was always depicted fairly straight, but most of the other characters in her stories were on the "cartoony" side. KO's for her were fairly rare, and bondage also seldom seen. Still, she always looked pretty good. I believe her various creators, particularly the famed Klaus Nordling wanted her to be PG, not PG 13 and certainly not anything sexier than that. Her alter-ego was Brenda Banks, a wealthy socialite heiress, daughter of a mine-owner. For a mask she wears a green see-through veil, something like a wedding veil only green. She has no superpowers but can throw a punch with the best of them. In this story she is investigating a crooked plastic surgeon who has operated on a suspected murderer and changed the felon's fingerprints. She gets KO'd, put on the surgeon's table, unmasked, and is about to be cut on when she suddenly wakes up and jumps off the table, engaging the staff in fisticuffs and in the end the bad guys lose and justice prevails. This is one of her rare KO scenes, and note how understated it is.
