Here is a link to a page with a
facsimile of the waltz that follows the
Trauerwalzer (and sounds like a variation of it) plus one other dance from D365, both in Schubert's hand (this is a
Reinschrift or fair copy, not a sketch). This is the second page of a two-page manuscript -- there are two schottisches and Schubert's signature on p. 1. Alternatively, you can go to the front page of
Schubert-Autographe and navigate your way to the dance autographs.
