Avant Le Duel, Jeune Homme Chez Le Maitre D-Armes Frederic Regamey

The picture has something of this: people, group, furniture, man, room, seat, leader, museum, monarch, indoors, woman, many, two, wear, several, royalty.
Perhaps it’s a painting of a group of people standing in a room with paintings on the walls and a piano in the foreground.
