A poster is any piece of printed paper designed to be attached to a wall or vertical surface.
Typically posters include both textual and graphic elements, although a poster may be either wholly graphical or wholly text. Posters are designed to be both eye-catching and informative. They are a frequent tool of advertisers trying to communicate a message.
Posters are also used for reproductions of artwork, particularly famous works, and are generally low-cost compared to original artwork.
