The MoMA exhibit "The Original Copy" presents a "critical examination of the intersections between photography and sculpture, exploring how the one medium has been implicated in the analysis and creative redefinition of the other." The exhibition posits the theory that photography grew up documenting sculpture. Tracing themes such as "the marvelous in the everyday" and "the readymade as reproduction", the exhibition presents photographs of works by Marcel Duchamp, taken by Alfred Stieglitz and Man Ray; Eug'ne Atget's photos of classical antiquities in France; Bruce Nauman's photos of his studio floor; and Christo's 441 Barrels Structure""The Wall" (Project for 53rd between 5th and 6th Avenues), 1968. There are many surprises to be found in the show, including the atmospheric views of Rodin's sculptures of Balzac emerging from the mist, taken by Edward Steichen, and a whole section of political images including a battlefield monument in Vicksburg, shot by Walker Evans.
