I found this in a huge stack of vintage prints. I convinced myself that it might be a well known star from early in the 20th century, but before I share my opinion I would be curious if anyone has a gut reaction as to the identity of the subject.
Well, truth be told I thought it was Gloria Swanson. She had a distinctive shape to the outside corners of her mouth - almost a bit like the corners of the Joker's mouth if you know what I mean. Also she had a very fine nose. I thought this model shared both features, along with Swanson's eyebrows and eye sockets. For added spice, here is the back of the print marked Steichen.
