Portrait of the writer Sergei Timofeevich Aksakov. 1872 Saratov Vasily Perov (1833-1882)

The picture has something of this: people, portrait, leader, man, facial hair, wear, elderly, side view, mustache, poet, profile, writer, pensive, politician, outerwear.
Perhaps it’s a close up of a painting of a man wearing a black shirt and a white beard.
