Stieglitz was O'Keeffe's husband, and he photographed her obsessively

The intimate photograph is one of only three prints known, and is the only one of those remaining in private hands. Available to view in a pre-sale exhibition that opens on September 28, the print is expected to sell for between $300,000 and $500,000.

Several iconic American photographs feature in the sale, with landscape photographer Ansel Adams represented by a group of five mural-sized images. The group is led by the awe-inspiring The Tetons and Snake River, which measures a huge 51½ inches by 39½ inches, and is expected to sell for $250,000-350,000.

Adams' Winter Sunrise will follow at $150,000-250,000.

Among European entries are three experimental works by abstract photographer Laslo Moholy-Nagy. A print of a Photogram from the 1929 Giedion portfolio is expected to sell for $20,000-300,000, while a print of one of his Hand Photograms, which also originates from the 1920s, holds an identical valuation.

Further highlights include a selection of artist's portfolios, which is headlined by Richard Avedon's Avedon/Paris, a seminal work from 1978 containing 11 of Avedon's signature fashion images. It is valued at $225,000-275,000.

More portfolios on offer include Ansel Adams' Portfolio VII ($80,000-120,000) and the 1993 self-titled portfolio by Ruth Bernhard, which comprises 10 platinum palladium prints of her most famous nudes.
