To use these posters and prints, simply choose a spot on your wall that you like, clean the area, and then hang them up with appropriate wall - hanging tools. Make sure the surface is flat and dry. As for maintenance, avoid direct sunlight for long periods as it may fade the colors. You can gently dust the prints with a soft, dry cloth. If there are any smudges, use a slightly damp cloth and wipe gently. Be careful not to apply too much pressure to avoid damaging the print.
