Mauve, Anton – Pieter Frederik van Os (1808-92), schilder, 1855 Rijksmuseum: part 3

The picture has something of this: people, woman, portrait, man, nude, veil, face, sculpture, girl, son, god, wear, wall.
Perhaps it’s a close up of a painting of a man in a black suit with a beard and a moustache on his face, looking off to the side.
