Teacher's manual for Prang's new graded course in drawing for Canadian schools
A teacher's manual for the Prang graded drawing course, issued by Gage in Toronto in 1901 for Canadian elementary school instructors. The plates are line diagrams of perspective construction — cubes with marked vanishing points, diagonal grids, receding planes — alongside soft pencil-shaded studies of spheres, cylinders and jars, giving designers ready geometric scaffolding and simple tonal renderings of basic solids.
