To use these posters and prints, you can simply hang them on your wall using a nail or a wall - hanging strip. For best results, choose a well - lit area in your room. When it comes to maintenance, keep them away from direct sunlight to prevent fading. If they get dirty, you can gently wipe them with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they may damage the print. Also, make sure the surface where you hang them is clean and dry to ensure a long - lasting display.
