This is a good, used copy of Mozart's Sonata for Violin and Piano K454.
These are some pencil marks on the violin score but the piano accomapniment is very clean but has been taped back together at the spine. (The pages are clean but not blank as this sonata was apparently accompanied by Mozart before he had a chance to write the accomaniment out!)
A useful clean copy of his Sonata.
Any questions, please feel free to get in touch.
