Consider what the 34-year-old Walker Evans did two days before the opening of his 1938 MOMA surveythe first exhibition in that venue ever devoted to a photographer. Evans didn't like how the curators installed his show, so he took down every photo, mounted a third of the pictures on cardboard and pasted them directly on the wall, then reframed and rearranged everything else. More artists need to act this way and take matters into their own hands. More are. Frankly, I don't think there's any choice.
