To use these posters and prints, simply pick a nice spot on your wall, use some nails or sticky hooks to hang them up. You can put them in your living room, bedroom, or even your office. Make sure the surface is clean and dry before hanging. As for maintenance, just use a soft, dry cloth to gently wipe off any dust every now and then. Avoid using harsh chemicals or abrasive materials, as they might damage the print. Also, keep them away from direct sunlight for long periods to prevent fading.
