In its 50 year history, the Pirelli calendar has depicted some of the most beautiful, famous faces (and naked bodies!) from supermodels like Kate Moss, Naomi Campbell, and Gisele, to celebrities like Jennifer Lopez and Penelope Cruz. Photographers snapping the legendary photos have included everyone from Herb Ritts and Richard Avedon to Karl Lagerfeld and Terry Richardson. Previous shoot locations include diverse international locales like Paris, Shanghai, London, Rio de Janeiro, and Naples, and U.S. Cities like Miami, Los Angeles, and New York City. The first-ever 1964 issue was shot by the Beatles' photographer, Robert Freeman and commissioned by the British subsidiary of the Pirelli Group, Pirelli UK Limited.
Much of the prestige behind the annual Pirelli calendar is that it's not available for purchase. Instead, around 20,000 copies are distributed exclusively to the world's top VIP industry executives and institutions, making it an instant collectors item with a cult following. (There are currently a handful in the hundred dollar range on eBay.) According to the UK Sunday Times (via Fashion Copious), models and photographers can't request to be included, they must be invited to participate, and sign everyone involved signs a non-disclosure agreement. This year's calendar will be revealed at an event in Milan on November 21. Until then, these anniversary photos should tide you over. By Joanna Douglas, Yahoo! Shine Senior Fashion & Beauty Editor
