Rough House Rosie (Frank R. Strayer, 1927) from the Paramount release book
"The most sensational female bet in pictures today is dimpled dynamite in this story of a girl who got her men by treating 'em rough. Clara Bow is THE box office discovery of 1927!"
This one's reportedly a lost film. Clara in boxing trunks, slugging it out? Who in their right mind would lose this one?
