The stage actress Martha-Bryan Allen (whose sister Elizabeth Allen was mother of "Bewitched" star Elizabeth Montgomery), circa 1920. View full size. G.G. Bain.
The Internet Broadway DataBase (www.ibdb.com) has her in Shaw's "Back to Methuselah" in 1922, playing "The Newly-Born". Since she seems to be hatching from an egg in this shot, I suspect that this identifies the production. It opened Feb 27, 1922, and ran for 25 performances.
Was this a publicity photo for a play?
