Work was performed on an 1891 Northwest Territories Liquor permit originally signed by then Lieutenant Governor of the North West Territories, Joseph Royal.

Liquor permit before conservation treatment showing the backing and the deteriorated cellophane tape.

After dry cleaning, the document was placed into a solution to remove the tape and the adhesive holding the document to the backing paper.

A close up view of the document in a chemical bath. The chemical released the adhesive holding the deteriorated tape in place.

The document, after removal of the backing and the tape, appears to have faded in different areas. It is still covered with an adhesive film.

The document, after the adhesive residue was removed, with the fragments that were previously held in place with the yellowed cellophane tape.
