Back in the day there was no such thing as Photoshop because computers were as big as a room and their main function was adding two plus two. Pin-up girls were not just an artists imagination or fantasies though - they were based on photographs of real models, and then drawn into the iconic images we fondly remembrer today.

Most of these models aren't too bad looking - but what's most interesting is that these look like they were shot in some guy's apartment. The standards of the day were also funny because you couldn't photograph a woman without her bra because that was considered pornographic, but you could draw her with out it and it was just 'naughty' at that point. Even though these are from the 1940s & 1950s, they still have a great sex appeal today.
