This is a used book published by Gendai Guitar. J.S. Bach French Suite for Guitar Duet Edited by Riichiro Manabe I acquired this used book over 30 years ago. As you can see, there are stains on the front and back covers. The music itself is very clean with no markings. There is some noticeable yellowing from age. Of course, there are no issues with performance. I hope someone can make use of it. (For the record, I have no pets and do not smoke.)
