5th Grade Science, 1972-73 (Showa 47-48) April to March issues, Gakken, 12-book set Books only (no supplements) The paper has discolored due to long-term storage, and there is some soiling on the covers. While there are no noticeable stains or tears, there are notes written in pen on the spines of 8 books (see photo 19). These books were originally priced at 220 yen. They are probably quite valuable now. The science that sparks children's interest is still enjoyable today. I hope someone who is nostalgic or interested will appreciate them. Thank you for viewing.
