The following is from the March 7, 2012 edition of the Baltimore Sun:
Document thief Barry Landau may have sold more of the national treasures he stole from museums — including the Maryland Historical Society in Baltimore, where his scheme unraveled — than previously thought, according to the National Archives inspector general, who said Wednesday that his investigators have uncovered new evidence.
Members of the agency’s Archival Recovery Team are now targeting historic document dealers who illegally, if unknowingly, bought pieces from Landau for $500 to $6,000 apiece, based on the disgraced collector’s own sales records, which were found during an FBI search of Landau’s Manhattan apartment.
