To use these posters and prints, you can hang them on your wall using picture hangers. Make sure the wall is clean and dry before hanging. Avoid exposing the prints to direct sunlight for long periods as it may cause fading. To keep them looking their best, gently dust them with a soft cloth every few weeks. If there are any smudges, you can use a mild, damp cloth to wipe them clean, but be careful not to soak the print.
