Pinup girl

A pin-up model (known as a pin-up girl for a female and less commonly male pin-up for a male) is a model whose mass-produced pictures see wide appeal as popular culture. Pin-ups are intended for informal display, i.e. meant to be "pinned-up" on a wall. Pin-up models may be glamour models, fashion models, or actors.

These pictures are also sometimes known as cheesecake photos.

The term pin-up may refer to drawings, paintings, and other illustrations as well as photographs (see the list of pin-up 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 on a postcard or lithograph. Such pictures often appear on wall or desk calendars. Posters of pin-ups were mass-produced and became popular from the mid 20th century.

Male pin-ups were less common than their female counterparts throughout the 20th century, although a market for homoerotica has always existed as well as pictures of popular male celebrities targeted at women or girls. Examples include James Dean and Jim Morrison.

In the late 19th century, burlesque performers and actresses sometimes used photographic advertisement as business cards to promote themselves. These adverts and business cards could often be found in almost every green room, pinned-up or stuck into "frames of the looking-glasses, in the joints of the gas-burners, and sometimes lying on-top of the sacred cast-case itself." Understanding the power of photographic advertisements to promote their shows, burlesque women self-constructed their identity to make themselves visible. Being recognized not only within the theater itself but also outside challenged the conventions of women's place and women's potential in the public sphere. "To understand both the complicated identity and the subversive nature of the 19th-century actress, one must also understand that the era's views on women's potential were inextricably tied to their sexuality, which in turn was tied to their level of visibility in the public sphere: regardless of race, class or background, it was generally assumed that the more public the woman, the more 'public,' or available, her sexuality", according to historian Maria Elena Buszek. Being sexually fantasized, famous actresses in early 20th-century film were both drawn and photographed and put on posters to be sold for personal entertainment. Among the celebrities who were considered sex symbols, one of the most popular early pin-up girls was Betty Grable, whose poster was ubiquitous in the lockers of G.I.s during World War II.
