Gustave Courbet – Self Portrait (LHomme a la Ceinture de Cuir) Part 3 National Gallery UK

The picture has something of this: people, portrait, man, woman, wear, music, facial hair, jewelry, musician, furniture, indoors, veil, position, writer, performance.
Perhaps it’s a close up of a painting of a man with his hand on his face and a book in front of him with a pen in his other hand.
