the rhetoric of images

Sherrie Levine http://www.afterwalkerevans.com/
This is a series created by Levine copied Walker Evans' photographs of workers in America during the great depression. Evans' work was very important as it showed "the poor farmer" and is still a very important series of photographic work, the series was used for the FSA to document the great depression for the press and also for educational purposes. Levine scanned these photographs in and displayed them as her work. Levine made no changes to Evans' work, she displayed them as Evans did. Levine's work questions originality and authorship and for me undermines the creativity that art is supposed to bring to the viewer. Reproducing work that has already been made, is she making this work viewable for a wider audience? yes.

Sherrine's work was then reproduced again. How many times can ones work be reproduced? I feel it does devalue the original work. I believe that art is creativity, and that the reproduction over and over again loses the original artist's intentions.
