Shogakusei zenshu; Sanjutsu no Hanashi.

1928. SAKAE, Okano. Shogakusei zenshu; Sanjutsu no Hanashi. Illustrated with one colour plate and numerous black-and-white illustrations and diagrams through the text. 8vo, 222 x 133 mm., bound in cloth backed publisher's illustrated card wrapper; illustrated title in red. Tokyo: Kobunsha, 1928. This is an arithmetic text book, which forms part of a set of 88 similar volumes. While the interior design is quite ordinary, the cover is quite spectacular. With some insignificant signs of aging, but in general a fine copy of a book, of which presumably very few copies have survived.
