Countess Nako Friedrich Von Amerling (1803-1887)

The picture has something of this: people, woman, portrait, music, dress, wear, two, jewelry, veil, Renaissance, musician, theater, kneeling, necklace, furniture.
Perhaps it’s a painting of a woman in a black dress sitting in a chair with her head resting on the arm of a dog, with a red curtain in the background.
