Plane and solid geometry
A school textbook of plane and solid geometry by James Howard Gore, published by Longmans, Green in New York in 1908 for secondary and early college classes. The plates are line-engraved geometric diagrams: lettered vertices, solid and dashed construction lines, parallelograms standing in for planes, pyramids and prisms drawn in oblique projection on cream paper, useful as clean vector-ready linework, abstract spatial motifs, or diagram textures.
