The Minneapolis Institute of Arts has unveiled a major expansion, and officials are hopeful that the ability to display a larger percentage of its collection will elevate MIA, which has always been considered a respected midsize institution, to the rank of top U.S. museums. “The new Target wing designed by Michael Graves is devoted to 20th-century art. There also are many more galleries for non-Western art, including six new Japanese galleries and one for art from the Pacific Islands.”
