To use these posters and prints, simply find a spot on your wall where you'd like to display them. You can buy a frame separately to make them look even nicer. When handling the prints, make sure your hands are clean to avoid getting dirt on them. For maintenance, keep them out of direct sunlight as it can fade the colors over time. Also, try to keep the area around them dry to prevent any damage to the paper. If there's a little dust on the prints, you can gently wipe it off with a soft, dry cloth.
