To use these posters and prints, simply find a nice spot on your wall. Clean the surface first to make sure the poster sticks well. You can use tape or poster putty to hang them up. Avoid hanging them in direct sunlight as it might fade the colors over time. To keep them in good condition, gently dust them off every once in a while. If there's a stain, use a soft, damp cloth to carefully wipe it. Don't use any harsh chemicals on them, as that could damage the print.
