Query: Beautiful book but little substance

I must say that I was greatly anticipating this book and had preordered the book. I have been to the author's store in New Hope and, although very pricey, had thought the store offered a good selection of Art Deco Lighting, including items made by Frankart, Nuart and Ronson. I was deeply disappointed when I received the book and found no Frankarts -- often viewed by collectors of American Art Deco as some of the best lamps made during the period and highly collectible -- with a few mediocre Nuart lamps pictured. The book is beautifully photographed and very clearly is a labor of love. It is just a great shame that there is little real substance included in the book to give a good overview to those who either truly collect, or are learning more about how and what to collect, lamps from the Deco period. I hope some other author provides a better offering the future.
