Adolph von Menzel (1815-1905) – The Balcony Room Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: room, house, indoors, furniture, architecture, door, window, home, family, wall, seat, building, doorway, vintage, decoration, interior design.
Perhaps it’s a painting of a chair and a mirror in a room with a rug on the floor.
