Studio of Jean Auguste Dominique Ingres – The Duc dOrleans Part 6 National Gallery UK

The picture has something of this: portrait, people, wear, man, model, music, profile, side view, lid, face, girl, jacket, fashion, facial expression, studio, fashionable.
Perhaps it’s a close up of a painting of a man with a scarf around his neck and a moustache on his face, wearing a black shirt.
