I actually like this little guide, because it's an interesting look at the past.
This slim book by Len Doust is a bit different in its teaching method. In his attempt to simplify the basic principles of perspective, he avoids standard teaching terms common to most other books: one-point perspective, two-point perspective, three-point perspective, vanishing point, etc. It's kind of interesting- he uses more words than he needs to to describe all these things, although he does cover these basics. About 33 pages have somewhat sketchy illustrations. Originally released in 1934 as Simple Perspective, I think Dover was very smart to re-title this the way they did.
Still, I really only recommend this for curiosity's sake, as a nice little blast from the past. If people are looking for more standard & in-depth perspective guides, my favorites include Perspective Drawing Handbook created in 1964, and Perspective Made Easy created in 1939. Both are still popular today.
