If you've ever wondered what artwork hides in private collections in the Twin Cities, now's your chance to find out. Nearly 200 pieces of art from local collections will be on display in an exhibit opening at the Walker Art Center in Minneapolis this weekend. The show is the result of months of searching by a team of Walker researchers, who asked collectors to temporarily share the contents of their living rooms. They found everything from Picassos and Lichtensteins to interesting works by lesser known artists. As the last pictures were going up, Curator Joan Rothfuss (ROTH fuss) told me about how a collection can tell us about its owner.
