Portrait of S. R. Ernst Zinaida Serebryakova (1884-1967)

The picture has something of this: people, portrait, man, wear, outerwear, jacket, sit, facial expression, indoors, mustache, writer, seat, facial hair, music, neckwear, actor.
Perhaps it’s a painting of a man in a white shirt and bow tie sitting in a chair in front of a bookshelf and a bookshelf.
