To use these posters and prints, simply choose a spot on your wall that gets enough light to show off the details. You can use regular picture hangers or frames to display them. Make sure to clean the wall surface before hanging. When it comes to maintenance, avoid exposing them to direct sunlight for long periods as it may fade the colors. If there's dust, gently wipe them with a soft, dry cloth. And that's it - enjoy your beautiful 'Night on Bald Mountain' posters and prints!
