NEW YORK (REUTERS).- More than 60 photographs by Richard Avedon, some rare and unpublished, will be auctioned next month by Christie’s in Paris to create the Richard Avedon Foundation endowment fund. The November 20 sale, the largest auction ever of Avedon’s work, is expected to fetch up to $6 million or more for the fund designed to help teach a generation flooded with technology to harness the power of photography. “We want to help organizations that use photography to tell the truth about things,” said Paul Roth, executive director of the Richard Avedon Foundation in New York. “We want to help young people learn how to use cameras and therefore have the power of controlling visual information in their own lives.”
