These vintage Amazing Spider - Man paperbacks are great collectibles. To use them, simply sit back, relax, and enjoy the classic stories. When handling, make sure your hands are clean to avoid staining the pages. For storage, keep them in a cool, dry place away from direct sunlight to prevent further discoloration. Try not to bend the covers too much to maintain their shape. If you notice any loose pages, you can use a little bit of acid - free glue to fix them gently.
