The Salon of Alfred Emilien, Comte de Nieuwerkerke (1811-92) at the Louvre, 1855 Francois Auguste Biard (1798-1882)

The picture has something of this: people, group, many, leader, performance, music, man, woman, room, ceremony, administration, furniture, meeting, musician, chair, education, wear, concert.
Perhaps it’s a painting of a large group of people sitting in chairs in a room with a chandelier hanging from the ceiling.
