The only handwritten draft of the Bill of Rights, by Roger Sherman

"A handwritten working draft of the Bill of Rights — the only such document known to exist — has been found and identified in the most likely of places: the Library of Congress. This early draft was written by Representative Roger Sherman of Connecticut on an unknown date in July 1789 while the first Congress was meeting in New York. Sherman, a longtime judge of the Connecticut Superior Court who became a Senator in 1791, served with Thomas Jefferson and Benjamin Franklin on the committee that drafted the Declaration of Independence. He was the only framer to sign all three original founding documents — the Declaration, the Articles of Confederation and the Constitution."
