To use these posters and prints, simply find a nice spot on your wall and hang them up using your preferred hanging method like nails or wall hooks. When handling, make sure your hands are clean to avoid getting dirt on the print. 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 they get a little dusty, you can gently wipe them with a soft, dry cloth.
