The term pin-up may also refer to drawings, paintings, and other illustrations done in emulation of these photos (see the list of pinup artists). The term was first attested to in English in 1941; however, the practice is documented back at least to the 1890s.
The pin-up images could be cut out of magazines or newspapers, or be from postcard or chromo-lithographs, and so on. Such photos often appear on calendars, which are meant to be pinned up anyway. Later, posters of pin-up girls were mass-produced. They became an instant hit.
Many pin-ups were photographs of celebrities who were considered sex symbols. One of the most popular early pin-up girls was Betty Grable. Her poster was ubiquitous in the lockers of G.I.'s during World War II. Other pin-ups were artwork, often depicting idealized versions of what some thought a particularly beautiful or attractive woman should look like. An early example of the latter type was the Gibson girl, drawn by Charles Dana Gibson. The genre also gave rise to several well-known artists specializing in the field, including Alberto Vargas, Gil Elvgren, and George Petty, and numerous notable artists, such as Art Frahm.
Other kinds of pin-upsIn comic books, a pin-up is simply a full-page piece of artwork, most often without dialogue, that showcases a character, group of characters, or significant event, published within an issue, rather than made available by itself as a poster.
In professionally published fan magazines for films and television series, a posed photograph of actors or actresses from the subject matter, but might also showcase specific scenes from the subject matter in photograph form (called stills) are occasionally called pin-ups. The label is very casual, though, as these types of fan media are more accurately described as posters.
