To use these posters and prints, simply pick a nice spot on your wall and hang them up. You can use tape or wall hooks, but make sure they're strong enough to hold the print. When handling the prints, try to keep your hands clean to avoid getting fingerprints on them. As for maintenance, keep them away from direct sunlight and moisture to prevent fading and damage. If there's a bit of dust on the print, you can gently wipe it with a soft, dry cloth.
