Used Yomiuri Shimbun Monthly "Grand Sumo" magazines from 1977 (Showa 52), issues 3, 5, 7, and 8, for a total of 4 books. These magazines are over 45 years old and show their age. They are not in good condition. There are bends, folds, and tears, but no pages have been cut out. As shown in the image, there is a small amount of writing on the back cover.
