古事類苑 第33冊
This is a Japanese reference volume, number 33 of the Kojiruien encyclopedia of old Japanese customs, compiled by the Jingu Shicho and published by the Kojiruien Kankokai in Tokyo in 1928 for scholars and general readers. Its four pictures are plain line diagrams of paper-making and book-making layouts: a boxed sheet, a vertical sheet with annotated columns, a frame with a curved mark and labelled panels, and a grid of numbered blocks. A designer might take their clean rules, spare line weight and grid-based structure as a model for technical layout.
