I enjoy listening to CDs while looking at sheet music, so this is sheet music I've collected. There are no markings or folds. I found a part that is torn on the first page, so please check the second image. There is some discoloration on the cover and back cover (image 8) due to aging, but it is not seen inside. Sheet music for Frédéric Chopin's Piano Concerto No. 1, 1959 edition. For two pianos. - Title: CHOPIN COMPLETE WORKS XIV CONCERTOS - Editor: Paderewski - Published: 1959 - Publisher: INSTYTUT FRYDERYKA CHOPINA - Work Number: Concerto No. 1 Thank you for looking.
