For the last 40 years Ed Rusha has been taking the ordinary things of American life and making them extraordinary. Considered one of the most influential of American Graphic artists ... he makes pictures of buildings, signs, and sayings, giving each a whole new meaning. This weekend the Walker Art Center opens a major retrospective of Rusha's work including his famous books of pictures of gas stations and parking lots. Rusha is in Minneapolis for the opening, and walked round the show with Minnesota Public Radio's Euan Kerr.
