John Dunlap produced about 200 first printed copies of the Declaration of Independence in 1776.
These sheets are known as Dunlap broadsides, the first published copies of the declaration. Congress sent the text to Dunlap, a Philadelphia printer, after approving it, and he worked through the night setting type and printing the broadside.
The figure is an estimate rather than an exact surviving production record. Historians do not know precisely how many were printed, but about 200 is the accepted estimate. The copies were distributed to the colonies, the Continental Army, and officials abroad so the declaration could be read and circulated quickly.
The Dunlap broadside is not the same object as the famous engrossed parchment copy with the delegates' signatures. The broadside was printed for rapid public distribution, while the parchment was prepared later as the official signed document.
