DALLAS, TX.- Fresh off a record-setting Banksy sale, a KAWS retrospective event and the groundbreaking DKE Toys Archive auction, Heritage Auctions goes big in the Urban art world by getting small. The Dallas-based house’s March 11 Urban Art event features only 43 lots. Yet the upcoming auction is a best-of-the-best sale highlighting some of the finest works by many of the biggest and brightest names on the global contemporary-art landscape.
