I really use this book. When I was young, I poured over it and used every page, either by drawing or painting copies of the plates. As an art teacher, I use his examples of composition, color and perspective. I used this book like no other in my library, so much so, that I'd worn the binding and the pages were slipping out. My dear mom, the librarian to the core, took it to a lady in Hillsboro, Oregon who repaired it for me. My mom told her that I wasn't as concerned with it's original condition as I was wanting to be able to continue to use the book. She did I wonderful job, so now it's sturdy and I can leaf through it again as I have all these many years.
Thank you Mr. Loomis. Thank you Mrs. Payne. Thank Mom.
I've seen a 1966 edition of this book on Amazon starting at about $200. Mine is a 1947 edition, but I image that the content is exactly the same. Here's a link to Amazon. I think it's a great investment!
