Portrait of Lieutenant P.E. Lvov Pavel Fedotov (1815-1852)

The picture has something of this: people, engraving, portrait, leader, etching, man, wear, antique, vintage, administration, military, royalty, soldier, prince, facial hair.
Perhaps it’s a black and white drawing of a man sitting in a chair with a dog in front of him and a dog laying on the floor next to him.
