To use these posters and prints, just find a nice spot on your wall, and you can hang them up with nails or adhesive strips. When hanging, make sure the surface is clean and flat. Avoid placing them in areas with direct sunlight for a long time, as it may fade the colors. For maintenance, you can gently dust them with a soft cloth. If there are stains, use a mild cleaning solution and a soft brush to clean them carefully.
