The outer cover shows signs of yellowing, scuffing, and deterioration. The main body has slight age-related yellowing, and there are traces of paper having been removed from a used bookstore. The monthly report is included. It is in good condition, I think it's in a clean state. I have taken photos to show the condition of the book as much as possible, so please take a look. Please understand that this is a used book before considering a purchase. Tsuneo Imura Katsumi Kakeda Toshiki Shimazaki Hitoshi Murakami
