Icons of American Photography at Frick
58 Photographs chronicling the evolution of photography from a scientific curiosity in the 1850s to one of the most potent forms of artistic expression in the 20th century.
It is free through January 3, 2010.
Also get you into southwest PA for some photography. I have not made it to Pittsburgh for the exhibit so no personal comments.
Icons of American Photography. This is a traveling exhibit from the Cleveland Museum of Art. It was on display there, Jun 24 - Sep 16, 2007. There are some really great works as outlined in your link. This is a wonderful exhibit of historic prints. Put it on your must do list.
