Declaration of Independence found in British Archives
A copy of the American Declaration of Independence has been discovered in Britain. The document, which is in perfect condition, is believed to be one of only 200 printed and was stumbled upon among files at the National Archives in Kew, southwest London, by an American doing research. Printed on July 4, 1776, it brings the total of known surviving copies worldwide to 26. The first official printings of the Declaration are known as Dunlaps because the name of the printer, John Dunlap, is given on each copy. A copy can be downloaded for free from the Archives site....
