Developed in the 19th century, the poster is a printed design of images and words on paper, produced in large numbers for the purposes of publicizing its subject through visual display. Its evolution was closely linked to the introduction of lithography, a printmaking technique which facilitates the rapid production of large editions. With the advent of colour lithography the poster reached its apogee as an art form. Its greatest exponent was undoubtedly Toulouse-Lautrec at the end of the 19th century, though it should be borne in mind that artists such as Lautrec produced the coloured drawings from which specialized master printers worked to produce the resulting poster. Most modern posters are produced by photolithographic means.
