Kaspar Karl van Beethoven, Brief an Breitkopf & Härtel in Leipzig, Wien, 27. August 1803, Autograph

Kaspar Karl van Beethoven offers the publishing house Breitkopf & Härtel in Leipzig different works by his brother: three small sonatas for piano (probably including op. 49,1 and 2), Variations for Piano Trio (probably op. 121a), the Variations for two Oboes and Cor Anglais WoO 28 as well as a Solo for Violin with accompaniment (probably the Romance op. 40). To refute Härtel's claim that Karl only sells works to him because he offers the most, Karl asks the "medium price" of 150 ducats for all the works offered.

On leaf 2r there are some calculations by the owner of the publishing house, Härtel, concerned with the works offered and their prices.
