Portrait of the composer PS Campioni. 1872 Astrakhan Vasily Perov (1833-1882)

The picture has something of this: portrait, people, man, elderly, wear, face, bald, mustache, facial expression, side view, facial hair, mammal, scientist.
Perhaps it’s a painting of a man with a long white beard wearing a black suit and tie with his hand on his chest and his right.
