To use these posters and prints, simply find a nice spot on your wall and hang them up using nails or adhesive strips. Make sure the surface is clean and dry. Avoid exposing the posters and prints to direct sunlight for long periods as it may fade the colors. To clean, use a soft, dry cloth to gently wipe away dust. If there are stubborn stains, you can lightly dampen the cloth with water and then wipe. Just don't soak the posters and prints. That's all there is to it! Enjoy your retro - looking wall decor.
