This is a great collectible book. When you're using it, handle it gently to avoid further wear. Keep it away from direct sunlight and humidity to prevent more foxing or darkening. If you want to clean it, use a soft, dry cloth to dust the cover and pages. When storing, place it upright on a shelf to maintain its shape. Be careful not to bend the pages or the dust jacket. And if you're displaying it, choose a place where it won't get bumped or scratched easily.
