Kristina Sabina (1643-1644), Princess of Holstein-Gottorp * Julius Strachen (?-1648)

The picture has something of this: people, baby, child, sculpture, statue, woman, portrait, wear, veil, dress, son, saint, god, girl, church, royalty.
Perhaps it’s a painting of a young girl in a gold dress standing on a balcony with a black curtain and a blue sky with white clouds in the background.
