A relentless photographer and image archiver, Jan de Cock collects his findings in hefty books dubbed denkmals (German for "monument"). The Belgian artist brings his roving eye to MoMA for Denkmal 11, a floor-to-ceiling photo installation depicting the museum's public and interior spaces, pieces from its vast archives, and other landmarks of American art, including Frank Lloyd Wright's Fallingwater and Jackson Pollock's Long Island studio. De Cock's different sized images, seemingly arranged in arbitrary compositions but actually conforming to a rigid grid, put modernist references in play both implicitly and explicitly. There's also an element of wry humor: look for the half-denuded Koons basketball in a image of the conservation studio.
