New Wells Fargo & Co. CEO Tim Sloan was in Des Moines today to help open a new 5,500-square-foot history museum in the Wells Fargo Bank lobby at 666 Walnut St. The museum showcases the shared stories of Wells Fargo, Iowa and U.S. history, and displays the Wells Fargo wagon in honor of Iowan Meredith Willson, the playwright who made the wagon famous in the Broadway musical “The Music Man.” It also includes a rotating art gallery that will feature about 20 pieces from the Wells Fargo collection by artists such as Andy Warhol, Alfred Stieglitz and Helen Frankenthaler. The gallery will feature local artists on occasion as well, and the museum will be one of the future stops along the new Art Route, a 6.6-mile painted connector path that will wind through downtown Des Moines from the state Capitol to Meredith Corp. The museum is expected to attract more than 25,000 visitors annually, and will be open weekdays from 8:30 a.m. to 5 p.m. Check out pictures of the museum here.
