Chopin Collection 1, published by Shunju-sha: Sonatas, Ballades, and Impromptus. The outer box has yellowing from long-term storage, and there are stains on the inside of the cover. The sheet music is unused and has no markings (apologies if I missed anything). Please understand this before purchasing. I would be happy if someone could use it. Thank you very much. Thank you for looking.
