In 1951, the Irish photographer Edward Quinn was living in Monaco with his future wife, Margaret, taking advantage of the splendid subjects on offer on the Côte d’Azur. For Life and Paris Match, he snapped impromptu shots of Grace Kelly, Aristotle Onassis, and Brigitte Bardot. The first time Quinn met Pablo Picasso, however, he left nothing to chance.

In July of that year, on a mission, Quinn traveled to a ceramics exhibition in Vallauris, France. “I was not the only one who wanted to see Picasso that day,” he said later, recalling how he pushed his way through a sea of cameras. Picasso posed with Prince Ali Khan, anticipating that a short photo op would be enough to appease the photographers. He was almost right. The crowd dispersed, but Quinn stayed. “It paid off,” he said, which was an understatement.
