To use these posters and prints, first find a nice spot on your wall where you want to display them. You can use regular wall hooks or adhesive strips to hang them. Since frames are not included, you can choose to frame them according to your own style. When it comes to maintenance, keep them away from direct sunlight to prevent the colors from fading. Also, avoid getting them wet. If there's a little dust on them, you can gently wipe it off with a soft, dry cloth.
