Portrait Of Friedrich Von Amerling Carl Christian Vogel Von Vogelstein (1788-1868)

The picture has something of this: people, portrait, man, wear, mustache, facial hair, jacket, leader, pensive, music, profile, cravat, tie, side view, scientist, neckwear.
Perhaps it’s a painting of a man with a beard wearing a black suit and bow tie and holding a large wooden easel with a red wall behind him.
