Portrait Of A Man Said To Be Leopold Desbrosses Jean-François Millet (1814-1875)

The picture has something of this: portrait, people, facial hair, man, mustache, engraving, poet, beard, writer, profile, vintage, wear, antique.
Perhaps it’s a black and white drawing of a man with a beard and a collared shirt, looking off to the side with a serious look on his face.
