One of the things I hate about price guides is the pricing. So many authors price items by what they have and what they want to have. If they have it, it's worth a fortune. If they want to have it, it's not worth anything. The reason for this is simple. If they want to sell something they have the price has been established and they'll ask the price in their book. It they don't have it and want it they price it low so they can buy it inexpensively. Keller and Ross don't do that. They are out there shopping, doing shows, going to auctions and their prices are generally right on the mark. That's a tremendous help to both collectors and dealers. The other great thing about the book is the photos. There are lots of them so it makes it easy to identify the pieces you have or are looking to buy. I like the organization by category which makes it easy to look up itemsIf you're a collector or a dealer this book is well worth the price.
