Dr. Joseph Klapp Thomas Sully (1783-1872)

The picture has something of this: portrait, people, man, wear, facial expression, outfit, outerwear, light, music, jacket, neckwear, menswear, room, musician, furniture, indoors, business, blazer.
Perhaps it’s a painting of a young man in a black coat and white shirt with his hand on his chin and his right hand resting his chin.
