To use these 'Devil in LA' posters and prints, first choose a great spot in your room. You can hang them on the wall using nails or wall hooks. If you want to display them on a table, use a poster stand. When handling the prints, make sure your hands are clean to avoid smudging. Keep them away from direct sunlight and moisture to prevent fading and damage. If there's dust on the print, gently wipe it with a soft, dry cloth.
