To use these posters and prints, simply find a nice spot on your wall and hang them up. You can use tape, thumbtacks or a picture - hanging kit. Make sure the surface is clean and dry before hanging. When it comes to maintenance, avoid direct sunlight as it may fade the colors over time. If they get dusty, gently wipe them with a soft, dry cloth. Don't use any harsh chemicals or abrasive materials as they can damage the prints.
