NARA’s copy of the first printing of the Declaration of Independence,more commonly known as the “Dunlap Broadside” underwent extensiveconservation treatment this past summer. The document, printedin Philadelphia the afternoon or evening of July 4, 1776 by John Dunlap, wasoriginally tipped into the Rough Journal of the Continental Congress and hadbeen extensively repaired over its lifetime. A NARA conservator carefullyremoved a fabric lining that was probably done in the early 20th century,followed by washing with buffered deionized water on a suction table to reducediscoloration and acidity. Remaining treatment steps included fillinglosses in the paper with a cotton/linen paper pulp followed by lining with twosheets of very thin Japanese mulberry tissue.
