The sketches are an exceptionally rare set, especially with the descriptive Key. All of the volumes appear to be complete, although we have not formally collated these volumes and some of the sketches have been annotated in ink. Viewing is recommended prior to purchase. The binding is slightly scruffy in places with sun damage. Volume 7 has some cracking to leather of spine. All have bumped spines and are slightly dog-eared. Internally the paper is foxed and slightly stained in places.
