Portrait of the artist I.S.Ostroukhov Valentin Serov (1865-1911)

The picture has something of this: people, man, elderly, facial hair, portrait, leader, wear, writer, administration, two, music, outerwear, war, mustache.
Perhaps it’s a painting of a man in a suit and tie sitting in a chair with his arms crossed and his right hand resting on a book in his lap.
