I have been collecting Nippon porcelain for 30 years and purchased my copy of this guide when it was first published in 1986. The price guide is obviously very out of date by now but is still a useful reference. The text is very informative / well written and includes an excellent history of Nippon from it's founding in the 1880's. The color photographs are invaluable in identifying "finds" as are the images of authentic Nippon backstamps. The author provides a helpful discussion of reproduction Nippon and how to tell it from genuine Nippon. Included as well are tips for photographing your collection for insurance purposes. The book is an excellent resource for either the novice or the advanced collector. Highly recommended.
