Pirelli Calendar Gals

This #ThrowbackThursday, we’re celebrating 40 years of sizzling Pirelli calendar gals because, dang, it’s cold out there, and we need to heat things up. The now-infamous (and highly exclusive) calendar launched in 1964 and has featured some of the biggest photographers (think: Richard Avedon and Annie Leibovitz) and models (see: Kate Moss and Naomi Campbell) in the entire fashion industry. Take a peek at some of our favorite shots from the ’60s until now, and we promise you’ll break a sweat.
