Portrait of Charles Nodier (1780-1844) Paulin Jean Baptiste Guerin (1783-1855)

The picture has something of this: people, portrait, man, cravat, jacket, wear, neckwear, menswear, tie, mustache, outerwear, popularity, facial hair, music, dinner jacket, outfit.
Perhaps it’s a painting of a man in a black suit with a white shirt and red bow tie and a black jacket and a blue sky in the background.
