Bogdanov-Belsky Nikolai Petrovich – Portrait of the Adjutant-General PP Hesse Hermitage ~ part 02

The picture has something of this: people, seat, wear, furniture, man, portrait, chair, room, indoors, sit, lid, outfit, group, veil.
Perhaps it’s a painting of a man in a military uniform sitting in a chair in front of a desk with a lot of other items on top of it.
