Anthony van Dyck – Prince Karl Ludwig of Palatinate (Carlo Emanule d’Este) Kunsthistorisches Museum

The picture has something of this: people, wear, portrait, man, woman, lid, royalty, child, jacket, two, veil, retro, son.
Perhaps it’s a painting of a boy in a black outfit with a chain around his neck and a butterfly on his arm, standing in front of a curtain.
