Paul Strand's Rebecca is the headline lot of a photography sale at Sotheby's New York on April 1, with a valuation of $300,000-500,000.
Strand was one of a group of boundary pushing artists in the early 1900s who coalesced around the photographer Alfred Stieglitz.
The present lot is one of a number of photographs Strand took of his wife Rebecca Salsbury between 1920 and 1932 (when they divorced).
Author Belinda Rathbone explained in an essay on the series: "Compared with his earlier subject matter these portraits of Rebecca seem effortlessly arranged; most important, they succeed in coalescing completely his art and his intimate life…
"Never again would Strand use his art to explore the facets of an intimate relationship".
A complete set of Nicholas Nixon's The Brown Sisters is valued at $200,000-300,000.
The images were taken between 1974 and 2013. Nixon had married Bebe (one of the sisters) in 1973 and took the first photograph at a family gathering the following year. This became an annual tradition.
One Brown Sisters portfolio sold for $180,000 at Sotheby's New York in 2005.
