Wilbeau Jacques (Château-Porsien 1729-1806) – Portrait of the Duke of Choiseul with companions (87x114 cm) ca1775 J. Paul Getty Museum

The picture has something of this: people, wear, group, theater, costume, woman, opera, dress, two, theatre, outfit, performance, man, music, royalty, three, veil, furniture.
Perhaps it’s a painting of two men and a woman sitting next to each other with a book in one hand and a cane in the other.
