This fall, Phillips will sell photographs from the Art Institute of Chicago’s illustrious collection. Works by Robert Frank, Henri Cartier-Bresson, Edward Weston and Irving Penn will be offered during sales in October in New York and in November in London.

The Art Institute of Chicago began organizing photography exhibitions in 1900 and has been building its own collection for nearly 65 years. Ellen Sandor, Chair and Curator of the Art Institute of Chicago’s photography department, said, “In 2014 we celebrate our fortieth anniversary as a separate curatorial department and the fifth anniversary of our dedicated galleries in the Art Institute’s Modern Wing. Those two anniversaries represent continuity and change—both essential to our progress. We have spent three and a half years to assess our holdings, with a view to refining and diversifying the collection as well as better understanding the treasures that we possess. Proceeds from the sale will support future acquisitions, and we are grateful to Phillips for working with such care and consideration on this sale.”

The two sales will be complemented by an online selling exhibition in December. Highlights from the collection will go on view in New York, Chicago and London prior to the sales.
