This picture was sold with the title 1930s Vintage Photobooth Smiling Handsome Boy? Holding Doll. It comes from a German photobooth. While it could be a boy, my feeling is, given the era, it is much more likely a little girl with her favourite friend.
In the days where certain illnesses or a lice infestation could prompt the shaving of a child’s hair, my guess is that this is a young lady recently recovered from one or other of those scenarios. There is also something coquettish about her gaze that I cannot acquaint with a young man. What do you think?
