新定画帖応用画集 第4学年
A 1911 Japanese school drawing textbook, the fourth-grade volume of a series of applied drawing exercises, illustrated by Ueji Itsutarō and published by him, aimed at pupils learning to draw. The pictures are plain line diagrams of boxes, blocks and rectangles in oblique projection with dashed construction lines and hatching, plus small Chinese-character measurement marks; a designer could take their clean, schematic linework and isometric-style box geometry as a model for technical diagrams.
