Portrait gr. Aleksei Alekseevich Perovskii (writer Anton Pogorelsky). Karl Pavlovich Bryullov (1799-1852)

The picture has something of this: people, wear, portrait, man, sit, woman, facial expression, child, music, retro, seat, outdoors, recreation, veil, lid.
Perhaps it’s a painting of a man sitting on a window sill with his hand on the window sill and his right.
