To use these posters and prints, you can easily hang them on your wall using nails or adhesive strips. Make sure the surface is clean and dry before hanging. Avoid hanging them in direct sunlight as it may cause the colors to fade over time. To keep them looking their best, you can gently dust them with a soft cloth every few weeks. If there are any stains, use a mild cleaning solution and a soft sponge to carefully clean the affected area.
