This 1956 portrait of Marilyn is featured in Cecil Beaton: Icons of the 20th Century, at Fundacion Canal in Madrid until August 19. It’s also the first Beaton retrospective held in Spain. “Beaton photographed Monroe in his Hotel Ambassador suite in New York, after she arrived an hour late,” the Guardian reports. “He later wrote that he forgave her for the delay in the moment because ‘her girlish ingenuity and cunningness broke my schemes’.”
