Different types of posters
Many posters, particularly early posters, were used for advertising products. Posters continue to be used for this purpose, with posters advertising films, music (both concerts and recorded albums), comic books, and travel destinations being particularly notable examples.
Propaganda and political posters
During the First and Second World Wars, recruiting posters became extremely common, and many of them have persisted in the national consciousness, such as the "Lord Kitchener Wants You" posters from the United Kingdom, the "Uncle Sam wants you" posters from the United States, or the "Loose Lips Sink Ships" posters[4] that warned of foreign spies. Posters during wartime were also used for propaganda purposes, persuasion, and motivation, such as the famous Rosie the Riveter posters which exhorted women workers during World War II that "We can do it!". The Soviet Union also produced a plethora of propaganda posters,[5] some of which became iconic representations of the Great Patriotic War. During the democratic revolutions of 1989 in Central and Eastern Europe the poster was very important weapon in the hand of the opposition. Brave printed and hand-made political posters appeared on the Berlin Wall, on the statue of St. Wenseslas in Prague and around the unmarked grave of Imre Nagy in Budapest and the role of them was indispensable for the democratic change. A recent example of an influential political poster is Shepard Fairey's Barack Obama "HOPE" poster.
Movie Posters
The film industry quickly discovered that vibrantly coloured posters were an easy way to sell their pictures. Today, posters are produced for most major films, and the collecting of movie posters has become a major hobby. The record price for a poster was set on November 15, 2005 when US$690,000 was paid for a poster of Fritz Lang's 1927 film Metropolis from the Reel Poster Gallery in London.
Travel posters
Poster advertising or proposing a travel destination, or simply artistically articulating a place have been made. An example is the Beach Town Posters series, a collection of Art Deco travel posters of American beach resorts that refer to the advertising style of the 1920s and 1930s.
In the early days of steam railways in Britain, the various rail companies advertised their routes and services on simple printed sheets. By the 1850s, with increasing competition and improvements in printing technology, pictorial designs were being incorporated in their advertising posters. The use of graphic artists began to influence the design of the pictorial poster.
Posters advertising events have become common. Any sort of public event, from a rally to a play, may be advertised with posters; a few types of events have become notable for their poster advertisements.
Concert posters
Many concerts, particularly rock concerts, have custom-designed posters that are used for advertisement of the event. These often become collectors items as well.
Blacklight poster
Blacklight posters are designed to have a special effect under a blacklight (ultraviolet light).
Pin-up posters
Pinup posters , "pinups," or cheesecake posters are pictures of attractive women designed to be displayed, first coming to popularity in the 1920s. The popularity of sexy pin-up girl posters has been erratic in recent decades.
Affirmation posters
This refers to decorative posters that are meant to be motivational and inspirational. One popular series has a black background, a scene from nature, and a word such as "Leadership" or "Opportunity."
Comic book posters
The resurgence of comic book popularity in the 1960s led to the mass production of comic book posters in the 1970s and onward. These posters typically feature popular characters in a variety of action poses. The fact that comic books are a niche market means that a given poster usually has a smaller printing run than other genres of poster. Therefore, older posters may be quite sought after by collectors.
