Pin-up model

A pin-up model is a model whose mass-produced pictures and photographs have wide appeal within the popular culture of a society. Pin-up models are usually glamour models, actresses, and fashion models whose pictures are intended for informal, aesthetic display, such as being pinned onto a wall. Beginning in the 1940s, pictures of pin-up girls were also known as cheesecake in the U.S.

The term pin-up refers to drawings, paintings, and photographs of semi-nude women. The term pin-up was first attested to in English in 1941. Images of pin-up girls were published in magazines and newspapers, and as postcards, lithographs, and calendars. The counterpart of the pin-up girl is the male pin-up, also known as beefcake, including celebrated actors and athletes such as the actor James Dean, the singer Jim Morrison, and the model Fabio.
