I have obtained a new copy and read it a few times. There are no markings or noticeable stains, but there is considerable creasing on the top and bottom of the cover. Please consider purchasing if you understand that this item has been stored at home. This is a gem and mineral encyclopedia in English, a hardcover book with a substantial feel. Please refer to the following page for details on the product: https://www.amazon.co.jp/-/en/Gems-Minerals-Treasures-Ontario-Museum/dp/1554078806
