Excerpt
This book will show you a way to draw airplanes, aircraft, and spacecraft. You need not start with the first illustration. Choose whichever you wish. When you have decided, follow the step-by-step method shown. Very lightly and carefully, sketch out step number one...Step number two is added right to step number one, also lightly and also very carefully. Step number three is sketched right on top of numbers one and two. Continue this way to the last step. The last step, and the last step only, should be drawn in firmly.
