Yushu (Philately) 1966, January - December, 12 volumes in total. Stamp collecting information. Japan Philatelic Association. Stamp catalog. The contents can be read without any problems, but the staples on image 6 are rusty and have turned brown. Page 7 is torn. There are scratches and stains on the exterior of the books, but the contents can be viewed without any problems. ☆ I will be gradually listing items that were at my parents' house or that I collected, as there are many of them. These were found while organizing my parents' house. I don't have detailed information, so please check the images. As they have been stored at home for a long time, there are some areas where the covers are faded, yellowed, or stained. Please understand that these are used books.
