Elzbieta Branicka, Countess Krasinka and her Children Franz Xavier Winterhalter (1805-1873)

The picture has something of this: people, group, wear, woman, three, two, portrait, dress, princess, bonnet, Madonna, veil, costume, man, theater, four, queen.
Perhaps it’s a painting of a woman, two children, and a woman in a red dress sitting.
