家事教材研究案 育児篇
A 1929 Japanese textbook on childcare, compiled by the Home Economics Teaching Research Society and published by Bunkōsha, meant for teachers and students of domestic science. Its pictures are plain black-and-white line diagrams: circular microscope-style fields of cells, a labelled cross-section of a fetus in the womb, and a side-view anatomical study of spine and body cavities. A designer might take their clean, schematic line style and their diagram-like labelling as a model for technical or instructional illustration.
