Pin-Up Girls Before and After II, 1950s posters
A pin-up girl, also known as a pin-up model or cheesecake, is a model whose mass-produced pictures see wide appeal as popular culture. Pin-ups are intended for informal display, e.g. meant to be "pinned-up" on a wall. Pin-up girls may be glamour models, fashion models, or actresses.
