Portrait of the pianist and composer Wilhelm Taubert Eduard Magnus (1799-1872)

The picture has something of this: portrait, people, wear, man, menswear, leader, dinner jacket, neckwear, outfit, music, confidence, facial expression, tie, jacket, business, cravat, musician, politician.
Perhaps it’s a painting of a man in a black suit with a white shirt and a black bow tie with his arms crossed and his right hand on his chest.
