This is a rare 1904 hardcover book. If you're a collector, just take it in your hands and enjoy the feel of history. When handling, make sure your hands are clean to avoid further soiling the pages. To maintain it, store it in a dry and cool place away from direct sunlight to prevent more tanning and staining. Since the spine is detached, be gentle when opening and closing the book to keep the pages firmly bound. Even though it has some wear, it's a great addition to any book collection.
