Portrait FF Rezanova. H. 1868, 91h71 pm, 5 GTG Vasily Perov (1833-1882)

The picture has something of this: portrait, people, facial hair, man, mustache, beard, wear, music, scientist, jacket, pensive, engraving, leader, vintage.
Perhaps it’s a portrait of a man with a long beard wearing a black jacket and holding a cane in his right hand.
