Today-Sunday: After a yearlong hiatus, the Minneapolis Institute of Arts has expanded and moved what was a high-end antiques show and sale. The new event will be held in St. Paul rather than Minneapolis and will showcase the wares of 39 dealers from around the country, including traditional silver and furniture. Map experts will be on hand, as well as specialists in 20th-century design, folk art, jewelry, Americana and vintage posters. The goods will still be authentic and museum-worthy, but at prices that don't always inspire gasps of amazement and dismay. Tours, talks and a design trunk show plus furniture on loan from Design Within Reach will ramp up the contemporary fun. To whet acquisitive appetites, the museum also has organized "Chairevolution! 300 Years of Designing the Chair," a special show that uses chairs from the collection to illustrate the ever-evolving history of design, from 18th-century English seats upholstered in satin brocade to the curvaceous plywood chairs that Charles and Ray Eames designed after World War II. Frank Gehry's "Cross Check Chair" of 1992 is shown here. (Design and Antiques Fair: 11 a.m.-6 p.m. today-Sat., 11 a.m.-4 p.m. Sun. $10. St. Paul Armory, 600 Cedar St., St. Paul.
