Query: You need this book

I bought this book as part of the 5 series volume. If you are beginner, a keen buyer/seller, or an experienced collector/trader of Nippon items, then you ought to get this book, along with the other series. The book contains a lot of information on Nippon porcelain collections. It provides nice photos, and price ranges on each items featured. It also gives you the marks to look and watch out for, in order to identify the authencity of the item.
