Carl Gustav Carus (1789 – 1869) – Balcony Room with a View of the Bay of Naples Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: window, house, wood, door, architecture, family, picture frame, indoors, wall, empty, room, home, doorway, furniture, light, decoration, glass items, interior design, inside.
Perhaps it’s a painting of an open window with a guitar in the foreground and a view of a city across the water from the balcony of a building.
