To use these posters and prints, you can easily hang them on your wall using regular picture hangers. Just make sure the wall surface is clean and dry. When it comes to cleaning, you can gently dust them with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they may damage the print. Store them flat in a cool, dry place if you need to take them down for a while. And enjoy the unique and mysterious atmosphere they create in your room.
