This AC/DC poster is a great collectible. To use it, you can unroll it carefully and hang it on your wall using suitable hanging tools. When handling the poster, make sure your hands are clean to avoid getting dirt on it. For storage, it's best to roll it up again and keep it in a cool, dry place. If there's dust on the poster, you can gently wipe it with a soft, dry cloth. Just be careful not to rub too hard to prevent damage to the edges where there's already some wear.
