This teen is posing with a CDV size piece of paper in his hand. He’s also sitting on what looks to be a hanging dark oil cloth. He’s resting his arm on some sort of machine behind him. A Difference Machine as was suggested by another collector? I’m not sure but this looks to me like it is photography or plate printing related. The seller thought it was a voting machine. A person suggested it is a balustrade, but I digress…I welcome opinions. What is it?
