Works on paper can be so much more than prints. They can be studies, drawings, paintings, and most importantly: works of art in their own right. This exhibition of works on paper encompasses the entire gamut. The Art Institute has organized the exhibition as a companion to the release of a book of the museum's modern collection except it is much more comprehensive than that. Many of these supporting works to their counterparts in the permanent exhibit show how much the artists' initial concepts can be just as if not more powerful than the finished works. Other works, are complete finished works on their own, and should not be missed. At the Art Institute of Chicago, through April 4, 2010, extended thru May 2, 2010.
