During ANTIQUES ROADSHOW's stop in Bismarck, North Dakota, host Mark Walberg gets a lesson in school-related antiques and collectibles from appraiser Karen Keane in an actual one-room schoolhouse, part of the Buckstop Junction historic village restoration. At the Bismarck Civic Center, appraisers give high marks to the array of objects brought for show-and-tell, including a painting of a Northern Pacific Railroad train that once may have graced a Fargo railroad station; a valuable Civil War photo collection of members of John Hunt Morgan's Cavalry, also known as Morgan's Raiders; and a delightful collection of University of North Dakota pottery, some made by the owner's mother and grandmother when they were students, valued at $5,500 to $ 7,500.
