To use these posters and prints, simply choose a spot on your wall where you want to display them. Clean the wall surface first to ensure better adhesion if you're using adhesive tape or hangers. You can use picture - hanging hooks or adhesive strips, whatever suits your wall type. As for maintenance, avoid exposing them to direct sunlight for long periods as it may fade the colors. If they get dirty, you can gently wipe them with a soft, dry cloth. Keep them away from moisture and sharp objects to prevent damage.
