In 1983, CCAHA Conservator Lois Price encountered a unique opportunity: the chance to treat the 1783 Treaty of Paris that ended the Revolutionary War. Price, who would go on to treat a copy of the Declaration of Independence written in Thomas Jefferson’s hand, conducted the contract treatment work on-site at the Library of Congress.

In the 200 years since the document was created, it had deteriorated due to natural aging and previous conservation attempts. At some point, the document was reinforced with silk that had become weak and brittle. It was also mended with an adhesive that had discolored. Price removed the silk and adhesive, mended tears, and consolidated the wax seals of the signers (including Benjamin Franklin and John Adams). The treatment was carried out as part of the Library of Congress’ celebration of the bicentennial of the document.
