小学錬画帖 巻之１
A Meiji-era Japanese drawing primer, Shōgaku rendōchō volume one, written by Matsubara Sangorō and published in 1886 by the Okayama prefectural normal school for elementary-school students learning to draw. The four pictures are bare geometric exercises: a bow-tie of two triangles meeting at a point, a curved-sided spike, a concave-sided square formed by four arcs, and two slanted lines with dots at their ends. A designer might take from them a stripped-down vocabulary of construction lines, tangents and intersections for building simple logo or pattern grids.
