高等小学新定画帖 : 男女生共用 第1学年
A 1912 Japanese drawing textbook (Kōtō shōgaku shin-tei gashō, first year, for boys and girls) issued by the Ministry of Education and published by Ōsaka Shoseki. Its pages are technical line drawings of solids, projections and oblique views, and a designer could take from them the clean geometric diagramming of orthographic and isometric-style construction.
