To use these posters and prints, simply find a nice spot on your wall and hang them up. You can use wall hooks or adhesive strips. When handling the prints, make sure your hands are clean to avoid getting dirt or oil on them. To keep them looking great, avoid hanging them in direct sunlight as this can fade the colors over time. Also, try to keep them in a dry place to prevent any damage from moisture. If they get a little dusty, you can gently use a soft, dry cloth to wipe them off.
