教案中心新定画帖教授の実際案
A 1917 Japanese teaching manual published by the Kyoiku Kenkyukai and written by Fujii Gosaku, offering practical guidance for classroom drawing instruction. Its pictures are line diagrams of geometric solids, with a cone and cylinder cut and shaded to show volumes, plus a hand holding a brush; a designer might borrow their clean, schematic diagram style and the way hatching shows cross-sections.
