||Wilhelm Altmann (1862-1951)
||Collegium Musicum, No.65|
Leipzig: Breitkopf und Härtel, n.d.. Plate 30828.
||Also listed as Kammermusik-Bibliothek Nr.1966. Third volume out of three from the uploader's library, cover left in its current digitally uncleaned state. In his 1937 preface, the editor fails to specify in what library he consulted the original edition which he surmises was probably issued at the composer's own expense, as each number was adorned with his portrait. The rest of his presentation is of interest with some useful details that are lacking in the wikipedia article.
