The kicker is, I can't draw!
But I do have a good memory, and this is a page I haven't seen in nearly 35 years. It is the assembly line method of drawing vehicles, done by Ed Emberley.
Emberley was an innovated artist who illustrated kids books. That may sound simple enough, but the complexity of his work and the sophistication of his methods put him among the best of 20th Century's graphic artists.
Amazing stuff, and his work has been saved and restored.
