A poster is any piece of printed paper designed to be attached to a wall or vertical surface. Posters are designed to be both eye-catching and informative. Posters, covers and brochures have been used since earliest times for advertising and announcements. Advertisement posters became a special type of graphic art in the modern age. Posters continue to be used for this purpose, with posters advertising films, music, comic books, and travel destinations being particularly notable examples.
