This book is NOT a design book! It is an excellent collection of retail graphics. The full-color illustrations are large enough to give you an overall idea without letting you steal the details. However, I was expecting it to be more organized from a design perspective.
Nonetheless, I'm glad I bought it! It's a good source of inspiration for color choices, shapes, and logotypes for signage and POPs. Not a great "reference" book per say, but every designer needs an "idea book" - this one just comes prepackaged! It's a good book at a good price.
