# Picture Book Library ① How the Subway is Made # Satoko Kako ② Album of the Universe # Masaki Morimoto # Sadazumi Okamura ③ My House is Being Built # Kunio Karai # Yukazu Kabayama This is a set of three books from the Fukuinkan Shoten Picture Book Library series, which can nurture a scientific mind. All of them do not have outer covers. All three books are readable without any problems, but please note that they are old and may show signs of wear and tear due to age. Regarding ③, there are noticeable spots on the first and last pages. I have included photos, although they may be difficult to see. Please consider purchasing after understanding the above. They will be sent via Yu-Packet Post with simple packaging.
