Despite having survived in remarkable condition, the Lincrusta-Walton of the Nickerson House required extensive conservation work. Over the decades the Nickerson Lincrusta had become increasingly brittle, and a century’s worth of grime, silt, and nicotine staining had accumulated over its surface. Conservators from Parma Conservation approached the Lincrusta as they would treat an oil painting that has darkened and discolored with age. This photograph shows an area of the Lincrusta wall fill on the south wall of the Dining Room prior to treatment.
