To use these posters and prints, you can easily hang them on your wall using nails or adhesive strips. Make sure to choose a clean and dry surface for a better hold. When it comes to maintenance, just use a soft, dry cloth to gently wipe off any dust. Avoid using harsh chemicals or abrasive materials as they may damage the prints. And be careful not to expose them to direct sunlight for long periods, as it could cause the colors to fade.
