4 Prints of American Historical Significance

Discoloration caused by dirt and acid contamination was a common theme for these four prints. Around the edge, tears were also problematic. Through a bevy of chemical baths and careful cleaning we were able to neutralize the acid components as well as lift a substantial amount of dirt particulates. For the tears we incorporated new paper of a similar quality to the original. Due to the thinness of the prints, and the susceptibility of the edges to tear, we archivally placed them on tissue paper to strengthen the backing.
