An American Journey

Christie's is auctioning the Diann G. and Thomas A. Mann Collection of Photographic Masterworks in October.  The 277 page catalog for the collection can be purchased from Christies, or it can be downloaded free as a pdf file.  This is an amazing collection of photographic images spanning a century of photography, with detailed notes for each item.  Thanks to Mike Johnston of The Online Photographer for the heads-up.
