Query: Perfect price, and a must have for fans

For me, it's well worth $20. With that said, I did spend the price that Amazon gave it, and am very satisfied with the contents. The renderings are for the most part fantastic. If you don't like one painting/sketching, you will usually find another one depicting the same thing further on. The book is divided into sections reflecting the various regions discussed in the book. Whether it is character depictions or scenic renderings you fancy the book is filled with either.The main focus of the book is art, so there are no real detailed descriptions of what you're looking at. For the most part you can use either the section or the title of the art as a quick guide. The only flaw with the whole thing I thought was the absence of an index to quickly look up paintings. I would've liked to have seen one of those. Other than that I highly recommend this book for any fan of Mr. Martin's series and don't mind paying $20 more than it should be as I did.
