Walker Evans: Decade by Decade (Review)

Cincinnati Art Museum's 'Walker Evans: Decade by Decade' opens with a rather bold statement that Evans is "probably the single greatest American photographer ever to have worked in the 20th century." An introduction like that certainly raises the stakes for an exhibition. I don't feel that, taken alone, the show proves he was the "single greatest" of the last century, but I also don't believe that's the show's objective.
