This same year a huge retrospective exhibition of the Photo-Secession was held at the Albright-Knox Art Gallery in Buffalo, New York. More than fifteen thousand people visited the exhibition over its four-week showing, and at the end the Gallery purchased twelve prints and reserved one room for the permanent display of photography. This was the first time a museum in the U.S. acknowledged that photography was in fact an art form, and, in many ways, it marked the beginning of the end for the Photo-Secession.
