Pretty arts for the employment of leisure hours : a book for ladies
An 1879 London handbook by Ellis A. Davidson, published by Chapman and Hall, teaching decorative handicrafts to women in their leisure time. The pictures are plain black-and-white line diagrams of geometric solids, a wood block with a shadow outline, and a perspective construction with vanishing point marked PS, showing how to draw and cut forms accurately. A designer could take from them a clear method for building simple three-dimensional shapes and projecting them onto a surface.
