To use these posters and prints, first choose a nice spot in your room. You can hang them on the wall using appropriate wall - hanging tools. Just make sure the wall surface is clean and flat. When it comes to maintenance, keep them away from direct sunlight to prevent the colors from fading. Also, avoid touching the printed surface with dirty hands to keep it clean. If there's dust on them, you can gently use a soft, dry cloth to wipe it off. And remember, since the frames aren't included, you'll need to get suitable frames if you want to display them in frames.
