To use these posters and prints, first choose a nice spot in your room to hang them. You'll need to get your own frame if you want one. Just measure the print and pick a suitable frame. When hanging, use proper wall hooks to ensure it stays in place. As for maintenance, keep them away from direct sunlight to prevent the colors from fading. If they get dusty, gently wipe them with a soft, dry cloth. Avoid using any harsh chemicals or water on the prints to maintain their quality.
