To use these posters and prints, simply find a spot on your wall that you want to decorate. Clean the area first to make sure the poster sticks well. If you're using tape or adhesive, apply it carefully to avoid wrinkles. When it comes to maintenance, keep them away from direct sunlight to prevent fading. If they get dirty, you can gently wipe them with a soft, dry cloth. Be careful not to use any harsh chemicals as they may damage the print.
