To use these posters and prints, simply find a nice spot on your wall and hang them up. You can use a picture hanger or sticky hooks. Since frames aren't 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 touching the print surface with dirty hands to keep it clean. If there's dust, you can gently wipe it with a soft, dry cloth.
