To use these posters and prints, simply pick a spot on your wall, measure it, and then hang them up using your preferred hanging method. Make sure the surface is clean and dry before hanging. As for maintenance, you can gently dust them with a soft cloth. Avoid using any harsh chemicals or abrasive materials. If they get a little dirty, a mild soap and water solution can be used on a soft sponge to gently clean the surface. Keep them away from direct sunlight to prevent fading over time.
