新式画帖 2巻
A 1909 Japanese picture book, the 新式画帖 (New-style Drawing Album) in two volumes, compiled and drawn by Komatsu Fumio and published by Katagawa Kensuke, presumably for students learning drawing and geometry. The pictures are plain line diagrams: a construction of an equilateral triangle with compass arcs, a right triangle, a scalene triangle labelled 不等邊三角形, and a pentagon inscribed in a circle with construction lines, each with simple Chinese-character captions set beside the figure. A designer might take from them the clean, precise linework and the geometric construction method for building shapes from arcs and bisecting lines.
