To use these posters and prints, first find a great spot on your wall where you want to display them. You can use wall hooks or adhesive strips to hang them up. When handling the prints, make sure your hands are clean to avoid getting dirt or oil on them. To keep them in good condition, avoid hanging them in direct sunlight as this can cause the colors to fade over time. Wipe them gently with a dry, soft cloth if they get dusty. And remember, since frames aren't included, you'll need to find or buy a frame that suits your style and the print size if you want to frame them.
