There is only one copy of the engrossed and signed Declaration of Independence, in the National Archives in Washington, D.C. This copy was produced and signed several weeks after the Declaration of Independence was first published.
It is estimated that John Dunlap produced 200 copies of his broadside of the Declaration of Independence, the first printing of the text. Of that original number, there are 26 known copies of the Dunlap broadside in the world today. The Dunlap broadside did not include any names besides John Hancock and Secretary Charles Thomson. The first broadside to include the names of the signatories was the Goddard broadside, printed in January 1777.
