A Portrait of Johan Claes Lagersvärd (1756-1863) Louis Gauffier (1761-1801)

The picture has something of this: people, wear, woman, man, two, seat, furniture, chair, leader, music, portrait, group, outfit, room, elderly, sit, indoors, theater.
Perhaps it’s a painting of a man sitting in a chair in front of a table with a red tablecloth and a bust.
