To use your 'Fall of the Moon' poster, you can simply hang it on your wall using a poster hanger or tape. It looks great in living rooms, bedrooms, or offices. When it comes to maintenance, keep it away from direct sunlight to prevent the colors from fading. If it gets dirty, you can gently wipe it with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials on the poster, as this could damage the surface.
