‘The works I add to my collection need to give me goosebumps’: Nicola Erni on the art she collects and why

Swiss collector Nicola Erni discusses her private art collection built over 25 years, focusing on photography from the 1960s and 70s, fashion photography by Helmut Newton, Mario Testino, and Annie Leibovitz, and contemporary works by Jean-Michel Basquiat and Andy Warhol. She recounts acquiring Warhol's 'Sixty Last Suppers' (1986), now on loan to Fondation Beyeler, and reveals her emotional decision-making process for purchases, as well as a regret over missing a Basquiat-Warhol collaboration at auction.
