Winterhalter, Francois Xavier – Portrait of Count Alexei Alekseevich Bobrinsky Hermitage ~ part 03

The picture has something of this: portrait, man, people, wear, veil, music, woman, lid, profile, side view, moon, exploration, retro, science.
Perhaps it’s a painting of a man in a coat with a hat on his head and a cane in his hand, standing in front of a brown background.
