Using these 'Expiration Date' posters and prints is easy. Just find a nice spot on your wall, and if you have a frame, put the print in it. Hang it up and enjoy your new wall decor. When it comes to maintenance, keep them away from direct sunlight to prevent the colors from fading. Also, avoid getting them wet. If there's dust on them, you can gently use a dry, soft cloth to clean the surface. That's all you need to do to keep your posters and prints looking great for a long time.
