What better way to celebrate the 40th anniversary of MASTERPIECE on PBS than by touring some of the stunning locations from the series? The MASTERPIECE 40th Anniversary Sweepstakes runs until Tuesday, 4/26/2011 and will send the grand prize winner and a guest on a four-day, three night trip to the United Kingdom. The trip includes VIP tours of Highclere Castle (Downton Abbey), Greenway (home of Agatha Christie), and Blenheim Palace (The Lost Prince), while enjoying accommodations with MacDonald Hotels & Resorts in the historic cities of Bath (Persuasion) and Oxford (Inspector Lewis).
