Fritzi Ritz was a popular comic strip in the 1930s but her niece, Nancy, outlasted her in popular culture. I was reading the Nancy and Sluggo comic strip in the 1960s, but didn't know about Fritzi until I started collecting paper dolls in 2003.
At first I thought this was Ruby Keeler, but this is an early film actress called Sally O'Neil. She was a WAMPAS Baby Star of 1926--a class that included Dolores Costello, Mary Astor and Joan Crawford.
WAMPAS--the Western Association of Motion Picture Advertisers--promoted budding young stars while also raising the profile of the publicity agents behind the star-making machinery.
Sally O'Neil's heyday was in the silent films of the 1920s.
