Beginning in the early nineteenth century, pin-up modeling had "theatrical origins",[3] burlesque performers and actresses sometimes used photographic advertisement as business cards to advertise shows.[4] These adverts and business cards could often be found backstage in almost every theater's 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.[5] "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.[6] 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.
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.[a] Cheesecake was an American slang word, that was considered a publicly acceptable term for seminude women because pin-up was considered taboo in the early twentieth century.[1]
The classic style of the pin-up originates back from the 1940s. Due to the shortages of materials during WWII, this period of makeup is considered the "natural beauty" look.[20] The US was immersed in war-time economy, which put distribution restrictions on consumer goods.[21] General rationing was supported; women applied mild amounts of products. Despite the rations, "Women were encouraged to keep buying lipstick and to send letters to the front covered in 'lipstick kisses' to boost the morale of the soldiers."
