Jacob Seisenegger – Portrait of Maximilian of Austria (1527-1576), Aged Three Mauritshuis

The picture has something of this: people, sculpture, portrait, wear, son, statue, man, lid, god, antique, child, decoration, costume, doll, ancient.
Perhaps it’s a close up of a painting of a child wearing a red and gold dress and holding a ball in one hand and a chain on the other hand.
