Full set vintage Charlie Brown's 'Cyclopedia

1980-1981 set of 15 books. Not opened much and in great shape. There is 'This book belongs to:' writing inside the covers of volumes 1 and 2. A few books had small white labels inside cover since peeled off (see pic). Some evidence of use on a couple bindings and small stains as shown. Have been in dry storage since the 80's but there is a slight musty smell which is fading.
