A sitter of the 1860’s posing with his hat on, and not with it on the table or knee. This looks like a short homburg. I don’t normally associate the 1860’s with this hat, so I like to have an early example of the period. He’s also wearing a ring on the pinky, and there’s a pineapple motif on the tablecloth. The photographer (and the sitter) didn’t care too much about the backdrop. The way it’s propped to the side is like it was put there as an afterthought.
By the type of lines framing this CDV, the picture was most likely taken between 1864 and 1869. There is no name or photographer info on the back.
