"The Thing and the Thing-in-Itself"

Curated by art historian Robert Hobbs, this show presents a group of key 20th-century artworks that each in their own way challenged the viewer's perception of what constitutes art—or even perception itself. Marcel Duchamp, Joseph Kosuth, René Magritte, Piero Manzoni, Yoko Ono, Ad Reinhardt and Robert Smithson are the featured contributors.
