These 'Mistress of All Evil' posters and prints are a great way to decorate your space. To use them, simply find a spot on your wall and hang them up. You can use your own frames or just tape them up if you prefer. When handling the prints, be gentle to avoid any creases or tears. Keep them away from direct sunlight as it can fade the colors over time. If they get dirty, you can use a soft, dry cloth to gently wipe them. Remember, frames are not included, so you'll need to get one if you want your print to have a finished look.
