To use these posters and prints, simply choose a spot on your wall where you want to display them. You can use regular wall hooks or adhesive strips to hang them up. Make sure the surface is clean and dry before attaching. As for maintenance, avoid exposing the prints to direct sunlight for long periods as it may cause the colors to fade. If there's dust on the prints, gently wipe them with a soft, dry cloth. Also, keep them away from moisture to prevent any damage.
