Sei solo a violino senza basso accompagnato. Libri primo, BWV 1001-1006. Faksimile-Druck des Autographs. [Staatsbibl. Preußischer Kulturbesitz, Berlin, mus. ms. aut. Bach P. 967;  Afterword in Ger by Wilhelm Martin Luther]. The copy of Ruggiero Ricci, with his ownership signature to the front free endpage and later handstamp of cellist Christine Walevska, to whom this was subsequently gifted by him. 21 x 33 cm, 44, iv pp. Handsome boards in marbled paper with pasted title plate. Spine covering mostly perished, but binding solid otherwise; light wear to edges and rear endpage, overall very good. 

Superb monochrome collotype of the 1720 autograph, issued on the occasion of Bachfest 1950 in Göttingen. One of the most beautiful and meticulous of all of Bach's manuscripts, here Bach clearly has taken performance from the autograph into consideration—by using comparatively large note heads, detailed articulation and phrasing marks, "custodes" that sit nearly throughout the manuscript at the end of each staff and anticipate the pitch at the beginning of the following staff, and by diligently planning the page layout with only few page turns, which are accompanied with the instruction "volti subito" (turn immediately).

This 1950 collotype is the very first facsimile of Mus. ms. aut. Bach P. 967 and this is a very special example indeed, from the library of the superb fiddler, specialist in the 19th century bravura repertory. A student of Persinger, Piastro and Kulenkampff, Ricci has been widely acclaimed for his technical prowess and was the first to record the 24 Paganini Caprices in their original version.
