Who Were They?

Today we have a British-looking fellow, only he’s got his hand tucked inside his vest. I don’t recall exactly why that became popular but for some reason I think Napoleon might have been involved. This man is sitting at a desk, as though he just turned from his work to greet his visitor (and scratch his chest), perhaps to discuss going hunting? Note his boots and his pants are somewhat tight, suggesting he might go riding after he finishes his conversation. This CdV did not have any photographer’s back mark, but the weight of the card places it somewhere after 1870. My guess is more toward the 1880s.
