What does Pirelli, a corporate tire company, have to do with gorgeous women? Aside from the pursuit of excellence, absolutely nothing. But that hasn't stopped the half-century-old calendar from becoming one of the most prestigious credits a model can attain. Choosing nothing but the most exotic locations with the most highly acclaimed photographers, Pirelli has created an exclusive product that is not sold in stores, but that is specially delivered to clients as a corporate gift. The calendar celebrates the artistic element of the naked female form, drawing a wide array of models.

In celebration of the calendar's upcoming 50th anniversary, we have ranked the top 50 models ever to appear in the Pirelli calendar. Although we can't show the pictures themselves, we have provided links to some of them. And we suggest you wait until after work to check them out. Enjoy!
