pôster

A póster is a printed paper designed to be displayed publicly, typically affixed to a wall or other vertical surface. Posters serve various purposes including advertising, announcements, propaganda, and decoration. They often combine visual graphics with text to convey messages effectively. Historically, posters emerged as a popular medium in the 19th century with advances in printing technology. They became particularly prominent during wartime for recruitment and propaganda efforts. The art form reached its golden age in the early 20th century with the development of artistic styles like Art Nouveau and later Art Deco. Modern posters are typically produced using offset printing, digital printing, or screen printing techniques. Common materials include paper, cardboard, and occasionally vinyl or other durable materials for outdoor use. The dimensions of posters vary widely depending on their intended purpose, from small handbills to large-format displays. Culturally, posters have become collectible items, with certain examples considered valuable works of art. They remain a popular form of communication in public spaces, advertising events, products, and social messages while also serving as decorative elements in homes and businesses.
