This collection is from my two aunts and grandmother who were all accomplished concert pianists. (I don't play well enough or often enough to do this collection justice.) There are a total of 8 boxes similar to the one in the picture posted. All alphabetical organized. They are are by the classical composers as well as others, some dedicated or written for my family. Music for two hands and four hands (possibly 2 pianos too). The music is 50+ years old and some well used, but most in excellent condition. I haven't sorted through because there is just so much.
Price is based on $20 value per box, but there is thousands of dollars worth.
