Applied perspective, for architects and painters
A technical manual on perspective construction by architect and critic William Pitt Preble Longfellow, published by Houghton, Mifflin in Boston in 1901 for practising architects and painters. The plates are line diagrams: numbered figures with vanishing points, picture planes, solid and dashed projection lines, and italic letter labels, useful as geometric line art, grid and axis motifs, or diagram textures.
