This comic is a collectible item, so you don't really 'use' it in the traditional sense. But if you want to look at it, handle it gently to avoid causing more damage. When storing, keep it in a cool, dry place away from direct sunlight to prevent further discoloration. If you plan to display it, use a proper comic book frame to protect it from dust and physical contact. Also, avoid bending or folding the comic as the binding, while solid, could be damaged over time with rough handling.
