Query: Ok, not great...

I was a little disappointed with this book. I was expecting a scholarly history, biographies of the inventors, inside stories, tales of invention and rivalry, etc... But the book really belongs more on a coffee table. There is an interesting, not-too-in depth essay at the beginning talking about the history and origins of the "Novelty Movement", but the rest of the book is dedicated to a picture dictionary with explanations and blurbs that are sometimes interesting, but not horribly informative. Whats in the Mystery Bag?? They never tell you! Frustrating purchase...
