Perspective, or, The art of drawing what one sees : explained and adapted to the use of those sketching from nature
A Victorian drawing manual by W. H. Collins, published in London by Longmans, Green in 1872, written for amateur sketchers working from nature. Its pictures are plain line diagrams of geometric construction: a vanishing point and horizon line, sight rays converging on a picture plane, and a simple house form in perspective. A designer could borrow the clean wireframe logic of these diagrams for layouts, grids, or technical instruction graphics.
