They're definitely not associated with any film studio or production company; the photographer is generally associated with New York theatrical and modelling subjects.
Gladys Rennick was a fairly petite model who could conceivably be the subject; the only image I have available of her right now is a poor-quality scan, so it's difficult to say.
What does the inscription say on the trophies she's holding? Because their function appears to be other than merely decorative, and could well provide a specific context for the images.
