What is Pirelli's calendar?

According to the company, The Cal "was born as an exclusive project" of the group's British subsidiary as they sought a marketing strategy to differentiate the brand from its competition in 1964.

The calendar was conceptualized as a gift to the tire maker's clients.

The Cal, per Pirelli, aims to "mark the passing of time with images by the most highly acclaimed photographers of the moment – capturing and interpreting contemporary culture and often anticipating new trends."

Idris Elba, Bella and Gigi Hadid, Kristen Stewart, Rosalía, Emma Watson, Cher and Iggy Pop are among the famous faces who appeared on The Cal in recent years.

The Cal's six-decade history boasts moments such as noted British fashion photographer Terence Donovan photographing only Black models, including up-and-coming teen talent Naomi Campbell, in 1987.

Karl Lagerfeld was the creative vision behind the 2011 calendar and renowned portrait photographer Annie Leibovitz was behind the lens of the 2000 and 2016 editions.
