To use these posters and prints, simply find a nice spot on your wall where you want to display them. Since frames aren't included, you can choose a frame that matches your decor style and put the print in it. When hanging, use proper wall hangers to ensure it stays in place. As for maintenance, keep them away from direct sunlight as it can fade the colors over time. Wipe them gently with a dry, soft cloth if they get dusty. Don't use any harsh chemicals or abrasive materials to clean them. Enjoy decorating your space with these beautiful artworks!
