Domenico DRAGONETTI (1763-1846). L.A., [Vienna 1810], to Andreas Streicher; 1page in-16, address. Rare letter from the double bassist to the Viennese pianist and piano maker. "Friend Clementi gladly accepts Mons Streicher's invitation to have soup with him tomorrow at one o'clock. But not in the least. He hopes that everything there was to glue will be ready, so that he can then try out the Mécanique." (Streicher's accounts with Dragonetti on the address page).
