To use these posters and prints, you can easily hang them on your wall with a nail or adhesive strips. When hanging, make sure the surface is clean and dry. Avoid placing them in direct sunlight for long periods as it may cause the colors to fade. To keep them looking their best, you can gently dust them with a soft, dry cloth every few weeks. If there are any stains, use a mild, damp cloth to wipe them, but be careful not to rub too hard as it may damage the print.
