To use these posters and prints, you can simply hang them on your wall with a nail or use adhesive strips. Make sure the surface is clean and dry before hanging. Avoid hanging them in direct sunlight for long periods as it may fade the colors. When cleaning, use a soft, dry cloth to gently wipe the surface. If there are stubborn stains, you can use a mild, water - based cleaner. Keep them away from sharp objects to prevent scratches.
