Portrait of the Countess de Martel de Janville known as Gyp 1894 Giovanni Boldini (1842-1931)

The picture has something of this: portrait, people, queen, famous, woman, person, antique, princess, wig, wear, royalty, engraving, retro, hair, veil.
Perhaps it’s a close up of a painting of a woman wearing a white wig and a black dress with a black ribbon around her neck and a diamond necklace.
