Museums do not usually like surprises, but the Minneapolis Institute of Arts (MIA) is planning an entire year’s worth of them. In honor of its centennial, the MIA is unveiling a series of high-profile international loans and public art projects without warning. The first birthday surprise, unveiled today, is "Woman Reading a Letter," around 1663, by Johannes Vermeer, which is on loan from the Rijksmuseum in Amsterdam until April 19.
