Wing Young Huie made his mark in the 1990s with his groundbreaking photo documentary of St. Paul’s Frogtown neighborhood. Several years later, he took on the entirety of Minneapolis’ Lake Street. Now he’s winding up his work on a six-mile stretch of University Avenue. Wing gives 3-Minute Egg a preview and invites the Egg along on a shoot at a small business along University. Wing is opening his studio to the public from noon to 10 pm Saturday to showcase his University Avenue Project photos for a preview sale. The exhibition goes up to the broader public in May along storefronts, the sides of buildings and giant projection screens along University.
