Portrait of Francois-Camille de Lorraine (1726-1788) Francois-Hubert Drouais (1727-1775)

The picture has something of this: people, portrait, man, person, wear, elderly, face, woman, coat, bald, leader, hair, indoors, sit.
Perhaps it’s a painting of a man in a fur coat holding a book in his right hand and wearing a white and black fur coat over his left shoulder.
