How to Draw - Book about Perspective

This is the new book I just started to study from:

It is a bit more technical/less artsy. It learns you about drawing in perspective in a high level. You can practice your knowledge with step-by-step tutorial examples of drawing machines (cars, aircrafts etc). I like it a lot!
I will send some posts when I am at the more interesting parts. Right now I am practicing how to do different transformations/transferences in perspective, but I find them not too spectacular for a post.
