A dim, high-ceilinged room. A fair-haired child in a pale silver dress stands in a wedge of light, flanked by attendants and a large dog. At the left a man stands behind the reversed back of a very large canvas, brush raised. At the rear, a small bright rectangle holds two indistinct figures, and a man stands in a lit doorway.
