Here and there, in some older houses, old faded daguerreotypes still hang on the walls... They seem to us to be very simple... compared with the artistic and skillful portraits made in later days... Here was a photograph that at one time had been the last word, a very modern portrait... Today it is just a part of cultural history. The small yellowed surface has acquired depth, an admonishing perspective. We hold in our hand a symbol of the structure and ideology of an epoch.
