There's a new exhibition of Photographer Alfred Stieglitz's iconic New York City photographs opening at the Seaport Museum today. (The late photographer, who was married to Georgia O'Keeffe, died in the city in 1946.) This is the first time the images will be shown together in almost 80 years; the exhibit features "an unprecedented group of legendary early twentieth century" photographs which will be separated into three galleries.

The first gallery evokes the spirit of 291, Stieglitz’s pioneering gallery, which cemented his reputation as an impresario of European modern art. It will include a facsimile of a lantern slide show, the first time Stieglitz’s lantern slides have ever been exhibited, and prints from 1893 to 1916.

The second gallery presents portraits taken from the windows of his midtown Manhattan apartment and gallery in the 1930s, when Stieglitz re-engaged New York as a subject for his photography.

The third gallery examines the explosion of imagery of New York in popular culture and fine arts, including works by renowned photographers Paul Strand, Lewis Hine and Berenice Abbott.

The images will be on display through January 2011, and here's a little preview.
