Poster & Print
Posters have been displayed in public places all over the world for more than 200 years. Visually striking, they have been designed to attract the attention of passers-by, making us aware of a political viewpoint, enticing us to attend specific events, or encouraging us to purchase a particular product or service. The modern poster dates back to 1870 when the printing industry perfected colour lithography and made mass production possible. Source: wikipedia (edited).
Film posters have been used since the earliest public exhibitions of film. They began as outside placards listing the programme of (short) films to be shown inside the hall or movie theatre. By the early 1900s, they began to feature illustrations of a film scene or an array of overlaid images from several scenes. Other posters have used artistic interpretations of a scene or even the theme of the film, represented in a wide variety of artistic styles.
A print need not be a reproduction of original art, be it oil or watercolour. Some prints are in fact original one-offs, perhaps created specifically for the artists' client. Otherwise it might be fair to suggest that a print typically sells in high numbers notwithstanding that there may be a limited print run or fewer signed and authenticated by the artist. Artist's proofs, of which there may be many, are not included in the count of a limited edition.
