Pin Up Gallery has a nice collection of pin-up calendars of 1940's and 1950's. There are fifteen calendars with beautiful illustrations of gorgeous girls from the magazines Ballyhoo and Esquire Girl, and drawned by two masters of pin-up illustration: Alberto Vargas and George Petty. Beyond the calendars, a set with 53 Vargas' pin-up playing cards. Just be careful with the transparency of the clothes of Petty's illustrations if you are at work.
