Far more than one of those thick books with modern layout and strangely-cropped images (which is what it appears to be on first glance). This book is a great read (even though there is only text on 1 out of 5 pages) and documents in photographs and words how the Freitag bag was developed, adopted by the masses, and used. If you want to see a product and design philosphy that is beyond "green", this is a good place to start. Smart, very smart.
