Mylar posters are limited edition prints, either released by movie studios or special limited edition authorized printers, that are printed on a sheet of mylar plastic. The plastic is then coated with either silver or gold paint and then the artwork is painted over the silver or gold paint, leaving holes to allow the silver or gold base paint to show through. Mylar posters are extremely colorful and attractive. Since this is an expensive process, these posters are printed in limited numbers.
