The annual MAC Art Auction, set for Saturday night at the Davenport Hotel, will look a little different this year. Sure, there will be plenty of works by locally and regionally known artists – Sister Paula Turnbull, the late George Flett, Harold Balazs, Kay O’Rourke, Ric Gendron, Mel McCuddin and Melissa Cole. But this year, there are fewer total works in the auction, and that’s by design, said Forrest Rodgers, executive director of the Northwest Museum of Arts and Culture.
