玉泉習画帖 簡易科 2
A Meiji-era Japanese drawing primer (ehon) by Mochizuki Gyokusen, published in 1892 by Tanaka Jirobei, meant for students learning to draw in a simple course. The pictures are crisp black-and-white woodblock-style sketches of a cluster of round forms on a branch, a flowering sprig with leaves, a pentagon with numbered corners, and a spiral diagram with Chinese numerals, so a designer can take their bold graphic silhouettes and clear step-by-step structure.
