Science for 6th Graders, 1973-74 (Showa 48-49) April to March issues, Gakken, set of 12 books Books only (no supplements) The paper has discolored due to long-term storage, and there is some blackening on the covers. There are no noticeable stains or tears, and no significant damage is apparent, but there are handwritten notes on the spines of 6 books (see photo 2). These books were originally priced at 250 yen. They are probably valuable books now. The science that sparks children's interest remains unchanged, and I think they will be enjoyable. I would be happy if someone is interested. Thank you for viewing.
