To use these prints and posters, first choose a spot in your room where you want to display them. You can hang them on the wall using nails or wall - hanging strips. Make sure the surface is clean and flat before hanging. As for care, keep them away from direct sunlight to prevent fading. If they get dusty, you can gently wipe them with a soft, dry cloth. Don't use any harsh chemicals or abrasive materials on them, as this could damage the print.
