This is a great collectible book. When using it, handle it gently to avoid any further damage to the dust jacket. If you want to preserve it, keep it in a dry and cool place away from direct sunlight. To prevent the pages from yellowing, don't store it in a humid environment. When reading, you can use a bookmark instead of folding the pages to keep the book in good shape. Enjoy exploring the wonderful plays and the beautiful costume notes and sketches inside!
