To use these posters and prints, simply find a nice spot on your wall, like in your bedroom or living room. Clean the wall surface first to make sure they stick well. You can use tape or picture hangers. When it comes to maintenance, keep them away from direct sunlight to prevent fading. Also, don't touch them with dirty hands to avoid stains. If they get a little dusty, you can gently wipe them with a soft, dry cloth.
