To use these posters and prints, simply find a nice spot on your wall, like in your bedroom or living room. Then, use appropriate hanging tools such as nails or adhesive strips to hang them up. Make sure to clean the wall surface first for better adhesion. When it comes to maintenance, avoid placing them in direct sunlight for long periods as it may fade the colors. Also, keep them away from moisture to prevent damage. If there is dust on the prints, you can gently wipe them with a soft, dry cloth.
