Caption: Gen. Henry Knox Trail Marker
Additional Description: Comparison of the Albany, New York (NY-21) Knox Cannon Trail marker as seen before restoration on the left(April 2008), and on the right after restoration (October 2009). Recently many of the Knox Cannon Trail bronze plaques have received conservation work to restore the original sculptural detail that had been lost over time. Typically these plaques are restored using a technique developed in consultation with the National Park Service, which uses a system of air abrasive cleaning with a compound of pulverized walnut shells to attain the original finish and then they are sealed with a lacquer coating.
