American text books of art education : Geometrical drawing
A drawing manual by Walter Smith, published in Boston by James R. Osgood in 1873 as part of a series of American art-education textbooks for schoolroom instruction in geometrical drawing. The plates are lettered construction diagrams—triangles, inscribed squares, tangent circles, bisecting arcs—drawn in solid and dashed line on cream paper, useful as line ornament, technical pattern, or diagram-style background.
