Visitors to the Speed Art Museum will get a bonus history lesson this summer. A rare limited edition 19th century copy of the original Declaration of Independence will go on display in an independence-themed exhibit Saturday.
By 1820, the original Declaration of Independence had already started to deteriorate. Secretary of State John Quincy Adams commissioned a copperplate engraving of the handwritten document from William J. Stone, who made about 200 copies on vellum.
