Conservators Rika Smith McNally (left) and Regina Gaudette work on a replacement nose for a bust of abolitionist John Brown in the Tisch Family Gallery at the Tufts University Art Gallery at Tufts University in Medford, Massachusetts, on Thurs., Oct. 6, 2016. The bust was sculpted by Edward Augustus Brackett and had been improperly stored for decades with a broken nose and eyebrow. The conservators, from Rika Smith McNally and Associates, found a plaster cast made from the original at the Boston Athen&aelig;um and had a 3D modeler image the broken section of the original and the cast. They then used 3D printing technology to use to create a plaster nose replacement that would fit perfectly on the broken marble bust. They then used gouache paint to match the replacement pieces to the original marble.  The bust is part of an exhibition at the gallery entitled &quot;Mortal Things: Portraits Look Back and Forth.&quot;
