To use these posters and prints, first choose a nice spot in your room to display them. You can hang them on the wall using appropriate wall - hanging tools. When handling, make sure your hands are clean to avoid staining the print. Keep them away from direct sunlight and high humidity as these can fade the colors over time. If there's dust on the print, you can gently use a soft, dry cloth to wipe it. Don't use any harsh chemicals or abrasive materials to clean them.
