To use these posters and prints, first pick a spot in your room that needs a touch of art. You can hang them on the wall using picture hangers or display them on an easel. When handling the prints, make sure your hands are clean to avoid smudging. To keep them in good condition, avoid placing them in direct sunlight as it can fade the colors over time. If there's dust on the print, gently wipe it with a soft, dry cloth. Don't use any harsh chemicals or abrasive materials to clean them as this can damage the paper and the print.
