Concert in the Galerie des Guise at Chateau d’Eu, 4th September 1843 Eugene-Louis Lami (1800-1890)

The picture has something of this: people, group, furniture, many, seat, chair, indoors, room, man, music, woman, chandelier, leader, table, ceremony, castle, performance.
Perhaps it’s a painting of a group of people sitting around a table in a room with chandeliers hanging from the ceiling and a chandelier.
