After serving for well over three years as creative agency for Famous Footwear, Campbell Mithun has announced that it’s declined to participate in the brand’s account review. The Minneapolis agency, which has its share of social media-loving interns, signed on as creative agency for the retailer back in January 2008 (Madison-based shop Hiebing previously handled the account) and subsequently worked on back-to-school projects as well as the “Make Today Famous” platform in 2009. CM’s CEO Steve Wehrenberg says in a statement, “We appreciate the invitation to participate, but realize that, moving forward, this partnership no longer serves our mutual business interests.”

Campbell Mithun’s contract with Famous Footwear runs out in August but before then, the agency will complete its seventh and final execution for the brand, which is a back-to-school 2011 effort.
