From Marina Abramović and Hiroshi Sugimoto to Herb Ritts and Edward Weston, Sotheby’s autumn photographs auctions offer images by legends of the medium, as well as cutting-edge artists. Our New York specialists, Emily Bierman and Aimee Pflieger, have selected their favorite works from the Contemporary Photographs and Photographs auctions, both on 3 October. Their highlights include photographs from Bob Seidemann’s Unspeakable Beauty series, a foray into the 1990s BDSM scene, – which appears at auction for the first time – and an ultra-rare daguerreotype of P. T. Barnum, whose life inspired the 2018 Golden Globe-nominated musical, The Greatest Showman. Click ahead to discover more about these remarkable auction highlights.
