Freehand perspective and sketching; principles and methods of expression in the pictorial representation of common objects, interiors, buildings and landscapes
A drawing manual by Dora Miriam Norton, self-published in Brooklyn in 1916 for art students learning freehand perspective and sketching. The line diagrams show books, chairs, boxes and empty rooms built up from eye lines, vanishing points and cast-shadow constructions, with hatched shading and lettered construction points — usable as schematic room shells, shadow-projection diagrams and labelled perspective grids.
