Johann Gottfried Schadow Julius Hübner (1806-1882)

The picture has something of this: people, portrait, leader, man, elderly, wear, politician, eyeglasses, outerwear, facial expression, pensive, business, facial hair, writer, jacket, scientist.
Perhaps it’s a close up of a painting of a man wearing a fur collar and a red bow tie and wearing a black coat with a brown fur collar.
