Leading the sale is Timothy O’Sullivan’s and William Bell’s, 'Photographs Showing Landscapes, Geological and Other Features, of Portions of the Western Territory of The United States, Obtained in Connection with Geographical and Geological Explorations and Surveys West of the 100th Meridian (Seasons Of 1871, 1872 And 1873)' (estimate $300/500,000*), known today simply as the Wheeler Survey. In the years following the Civil War, America experienced a golden age of survey photography. O’Sullivan’s and Bell’s photographs in the present album are some of the most remarkable views of the American West ever created. The present album, consisting of the complete 50 photographs – 35 by O’Sullivan and 15 by Bell – is exceptionally rare and the first to appear at auction in over three decades.

Other notable early photographic works include William Henry Fox Talbot’s Sun Pictures in Scotland (estimate $30/50,000) recognized as the first photographically illustrated book completed for public sale, Horatio Ross’ pastoral landscape Untitled (Sea Coast Near Netherley) (estimate $20/30,000), as well as salt prints by David Octavius Hill and Robert Adamson.

Turn of the century photography includes F. Holland Day’s haunting allegorical portrait St. Sebastian (estimate $200/300,000) an indisputable masterpiece demonstrating the artist’s unique vision and command of the platinum process. Another captivating platinum print is Edward Steichen’s early Self-Portrait (estimate $100/200,000) from circa 1900. In the intimate portrait, the artist’s face and suit are rendered with striking detail and impressive tonal range. Steichen’s self-portraits from this period are exceptionally rare. Works by Eugène Atget, Heinrich Kühn, and Gertrude Käsebier are also featured.

Modernism is well represented throughout the sale. An impressive selection of iconic Ansel Adams photographs is highlighted by his powerful mural-sized Sierra Nevada from Lone Pine, California (Winter Sunrise) (estimate $180/220,000) originally from the collection of Pulitzer Prize-winning author Wallace Stegner, who shared with Adams a steadfast commitment to environmental conservation. Early prints of Edward Weston’s Shells (estimate $150/250,000) and Dunes – Oceano (estimate $100/200,000) exemplify the artist’s ability to experiment with different compositions, depth of field and exposure times while capturing the tonal quality of different surfaces.
