Sanpei Shirato's Sanada Kenryu, complete 3-volume set. Volume 3 also includes the short story "Jinshin-numa Ihen" (Strange Incident at Human Body Swamp). While there are no noticeable scratches, stains, or tears, there is some yellowing and discoloration due to aging, so the condition is listed as "slightly damaged or with stains." Considering the books are 50 years old, I think the preservation condition is quite good.
