The history of the ‘pin up girl’ is fascinating, with a brief outline dating pinups back to the 19th century, reproduced below courtesy of Wikipedia.
A pin-up girl or pin-up model is a model whose mass-produced pictures see wide appeal as pop culture. Pin-ups are intended for informal display. Pin-up girls are often glamour models, fashion models, celebrities, and actresses.
The term was first attested to in English in 1941; however the practice is documented as dating at least to the 1890s.
Many pin ups were photographs of celebrities. 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.
The genre also gave rise to several well-known artists specializing in the field, including Alberto Vargas . (Source Wikipedia)
