Ludwig van Beethoven, Billet an Ignaz von Gleichenstein, Wien, November oder Dezember 1808, Autograph

Beethoven invites his friend Gleichenstein to dinner that evening on behalf of Countess Erdödy (Beethoven was living at her house at the time). Beethoven asks how much people are prepared to pay for a piano in Freiburg, and reminds Gleichenstein to bring the quills which he has requested.
