"Giant Beavers and Moose was full of tears, holes, and missing strips. New patches had to match the original surface, down to the weave of the canvas. Using silicone, Campbell made molds of the painting's surface, then spread thin layers of a waxand-resin compound over the gaps, and finally ironed on the silicone impressions of the canvas texture. With the surface even, the missing parts of the composition were reconstructed using paints made from hand-ground pigments in a modern synthetic medium."
