SILVER: the 25th Cooperative Exhibition

Opening Friday: Under the skylights in Highpoint's spacious workroom, dozens of Minnesota artists sketch, ink and run their plates through the center's etching presses. Then they check their proofs and start all over, refining their designs until they're satisfied with the concepts. For the "Silver" show, 37 members of the Highpoint cooperative have turned out a sparkling variety of images, ranging from North Woods landscapes to abstractions and whimsical interpretations of summer, as seen here in "My Minneapolis" by Miriam Rudolph, who is obviously a bicycle enthusiast and culture consumer. Note bikers rolling along a Midtown Greenway lined with farmers-market vendors, rowers on the Mississippi near the Weisman Art Museum, the Minneapolis Sculpture garden and Walker Art Center, and the Minneapolis Institute of Arts' Dale Chihuly chandelier illuminating the whole scene. (Opening, 6:30-9 p.m. Fri., free. Highpoint Center for Printmaking, 912 W. Lake St., Mpls., ends Aug. 23, free, 612-871-1326 or
