Book excerpt: The Unfinished Exhibition, the first comprehensive examination of American art at the Centennial, explains the critical role of visual culture in negotiating memories of the nation’s past that conflicted with the optimism that Exhibition officials promoted. Supporting novel iconographical interpretations with myriad primary source material, author Susanna W. Gold demonstrates how the art galleries and the audiences who visited them addressed the lingering traumas of battle, the uneasy re-unification of North and South, and the persisting racial tensions in the post-Emancipation era.
