To use these posters and prints, simply find a nice spot on your wall, like in your bedroom or living room. Use a thumbtack or wall adhesive to hang them up. Be careful not to bend or crease the prints during handling. To keep them in good condition, avoid exposing them to direct sunlight for long periods as it may fade the colors. Also, keep them away from moisture. If there's dust on the prints, you can gently wipe it off with a soft, dry cloth.
