Original playbill, Vienna premiere of Don Giovanni Coffee Mug

Original playbill for the Vienna premiere of Don Giovanni. Don Giovanni, (K. 527; complete title: Il dissoluto punito, ossia il Don Giovanni, literally The Rake Punished, or Don Giovanni or The Libertine Punished) is an opera in two acts with music by Wolfgang Amadeus Mozart and Italian libretto by Lorenzo Da Ponte. It is based on the legends of Don Juan, a fictional libertine and seducer, by Spanish writer Tirso de Molina. It was premiered by the Prague Italian opera at the National Theater (of Bohemia), now called the Estates Theatre, on 29 October 1787. Da Ponte's libretto was billed as a dramma giocoso, a common designation of its time that denotes a mixing of serious and comic action. Mozart entered the work into his catalogue as an opera buffa. Although sometimes classified as comic, it blends comedy, melodrama and supernatural elements.
