To use these posters and prints, first choose a nice spot in your room. You can hang them on the wall using a poster hanger or tape, depending on your preference. When handling the prints, make sure your hands are clean to avoid getting dirt on them. To keep them in good condition, avoid exposing them to direct sunlight for long periods as it may fade the colors. Also, keep them away from moisture. If there's a little dust on the print, you can gently use a soft, dry cloth to wipe it off.
