He has long, slender and tanned hands, and these look like working ones too, almost as if they should belong to someone older than him. This could be my imagination but the top of his head looks lighter, as if he worked outdoors a lot but wore a large brim hat. The young woman by his side I can only assume is his wife is resting her hand on his arm, and her white (cotton?) top is interesting; simple but nice, wrapping down over her skirt. It was accessorised with a pearl necklace, leaf brooch and belt. All this makes me think this was taken in the summertime.
He’s wearing a type of necktie/scarf popular of the 1870s-80s.
