One of the biggest highlights of Heritage Auctions’ upcoming Photographs Auction will be the camera used a half-century ago by photographer and environmentalist Ansel Adams. The auction will be taking place on October 27, 2016.

The camera was used by Adams for shooting the well-known 1968 image Arches, North Court, Mission San Xavier Del Bac in Tucson, Arizona and other famous photographs of that era.

“This is the only Ansel Adams’ view camera ever offered at auction,” said Nigel Russell, Heritage Auctions Director of Photography. “After he used this camera between 1964 and 1968 he gave it to his assistant, Lillian DeCock, who also became a distinguished photographer. This camera and equipment, along with four other cameras used by DeCock and her husband, were consigned by her heirs.”

Another significant lot in this auction is a rare and complete set of the six alternative photos for The Beatles’ iconic Abbey Road album cover, which were taken and autographed by Iain Macmillian in 1969. Five of these shots show the Fab Four walking across the street at Abbey Road, and one of them has them walking in the opposite direction of the photo eventually used for the album cover.

Modern and contemporary photographs include Hiroshi Sugimoto’s Celtic Sea, Boscastle (Day), 1994 (est. $20,000-30,000) as well as his Hi-Way 39 Drive-In, Orange, 1993. The work of Robert Mapplethorpe is represented by his contemplative portrait of Clifton Taylor, 1981 (est. $10,000-$15,000) and Lisa Lyon, 1980 (est. $10,000-$15,000). Also in the sale is the haunting post September 11 scene Brooks Brothers, September 12, 2001, (est. $10,000-$15,000) by Sean Hemmerle.
