NEW YORK, NY.- On March 31, Christie’s will present 20/21 Photographs. With over 140 lots, this sale is comprised of an extensive selection of classic works by artists such as Alfred Stieglitz, Edward Weston, Richard Avedon and William Eggleston among others. The sale will follow on the single-owner sale of Leaves Of Light And Shadow: Photographs Gathered By William T. Hillman.

Leading the sale is Alfred Stieglitz’s Georgia O'Keeffe, 1918 (pictured above). Over a period of roughly twenty years, Stieglitz produced a group of over 300 portraits of Georgia O’Keeffe. Relatively early in their relationship, Stieglitz made this stunning image, printed in platinum. Posed in front of one of her charcoal drawings, there is an obvious sensuousness—evidence of the shared passion between the two artist. The present lot is the only known print of this image to come to market from the Estate of Georgia O'Keeffe.

EDWARD WESTON, Dunes, Oceano, 1936, gelatin silver print Estimate: $100,000 – 150,000
• This print is from the period when Weston was at the height of his creative powers. The tonal range extends from a deep black in a foreground dune to a bright white in the background sky.

• Weston used the whole frame; he includes not only a horizon line, but a sky with clouds that compliment and interact with the shadows and sand below.

ÉTIENNE-JULES MAREY, Vol du Goéland, c. 1883-87, chronophotographic albumen print | Estimate : $25,000-35,000
• Vol du Goéland was reproduced in the December 5, 1887 issue of La Nature

• The print was originally given by Marey to Gaston Tissandier, editor of La Nature from 1873-1945.

• The two pencil strokes that can be seen on the image delineated the area to be reproduced in the magazine and annotations 'Use only four birds and reduce to fit into the wood’ on the reverse of the mount are believed to be in Tissandier’s hand.

• The photograph remained in the Tissandier family until 2006.

RICHARD MISRACH, Untitled, from On the Beach, #763-03, 2003, chromogenic print
• Photographing from high atop a building perched near the Pacific Ocean, the beach below Misrach is peopled with a range of figures.

• This large scale print is 48 inches tall by 86 inches wide, and is sold framed.

• Misrach’s On The Beach exhibition premiered at the Art Institute of Chicago in 2007 and travelled extensively the following two years.

MICHAEL COOPER, Sergeant Pepper’s Lonely Hearts Club Band, 1967, dyetransfer print | Estimate: $50,000 – 70,000
• Sergeant Pepper’s Lonely Hearts Club Band is a pristine and unique print and is in a broader cropping than the album cover showing much 'behind-the-scenes’ activity.

• In keeping with the lyrics of the title track, Paul’s idea was that the group should be depicted as the kind of band that would play in a park bandstand.

• This is the only known dye-transfer print of the image.
