Chopin Etudes, Cortot edition, op. 10 and op. 25, a set of 2 books. These are quite old, so there are stains and yellowing. A protective film is attached to the cover. The cover of op. 25 has come off. There are pencil markings, and the name on the last page has been erased. There is no problem with reading the music, so how about using them as reference scores? Please consider only if you can accept the condition. Etudes, imported edition, Alfred Cortot, English commentary Chopin 12 Studies, Black Key Etude, Winter Wind
