Flandrin Hippolyte Joseph Charles Paul prince Napoleon Hippolyte Flandrin (1809-1864)

The picture has something of this: people, portrait, man, wear, menswear, neckwear, jacket, music, musician, blazer, outfit, outerwear, mustache, light, facial expression, coat, tie.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with his hands on his knees and his right hand on his hip.
