This posthumous portrait of Wolfgang Amadeus Mozart was painted by Barbara Krafft at the request of Joseph Sonnleithner in 1819, long after Mozart died. Sonnleithner, who was making a "collection of portraits in oils of well-known composers" (Deutsch) wrote to Mozart's still-living sister Maria Anna ("Nannerl"), asking her to lend a picture to Krafft (a well-known artist working in Salzburg).
