Two separate violin parts for the Violin Concertos Number 2 and 15. As follows: 

[No. 2] 2me Concerto A Violon Principal Deux Violons Alto et Basse 2 Hautbois 2 Cors. Disbound upright folio. Engraved. [PN] 1142. Title, fol.1r blank, 2-10 pp. Publisher's signature, "Sieber," to right foot of title. First edition, probably later issue. Plate number suggests 1791 as the date, but title seems to be more recent. The work was composed in 1784-85. In fine condition. 

[No. 15] Concerto C A Grand Orchestre...  Paris: Cherubini, Méhul, Kreutzer, Rode, N. Isouard et Boieldieu, n.d. [ca. 1805]. [PN] 324. Title; note to verso of title ((translated from French): "Note to the music lovers: All new works by Kreutzer will be designated by the letters of the alphabet and will be exclusively published in Paris by Cherubini, Méhul and Company." 1-11 pp.; final page blank. Hand stamp "Kreutzer" to right foot of title. Signature of "Le Menue" to right head and foot of title. Note in pencil to head of first page of music: "Bon pour concours" (good for a competition). The "numbering" by alphabet is confusing to English and German speakers, who would interpret "Concerto C" as "Concerto in C." it is no surprise that this unorthodox method of counting did not catch on. First edition.

The French violinist and composer Rodolphe Kreutzer was one of the most famous and influential virtuosos of his time. From 1795 he was professor at the Paris Conservatory, and from 1801 to 1821 he was concertmaster and director of music of the Paris Opera. At this time, Kreutzer wrote about 40 operas and numerous works for violin. In 1803, he published together with Jacques Pierre Joseph Rode and Pierre Marie François Baillot the "Méthode de violon" ("System for the violin"), which soon after had become the official manual of exercises for the violin at the Paris Conservatory. Kreutzer befriended Ludwig van Beethoven during his visit to Vienna in 1798 and Beethoven later wrote that he was "a good and nice person, it was indeed a pleasure to spend time with him". Seven years later (1805), Beethoven dedicated his Violin Sonata in A Major, op. 47 to Rodolphe Kreutzer, now known as the "Kreutzer-Sonate".
