Plane and solid analytic geometry; an elementary textbook
Charles H. Ashton's Plane and Solid Analytic Geometry, an elementary textbook issued by Charles Scribner's Sons in New York in 1901 for American college students. The 92 line diagrams plot conics, tangents, and coordinate axes in thin black stroke on cream paper, with serif italic point labels — usable as clean geometric linework, axis motifs, and curve outlines.
