Scratchboard drawing. I us a small fiberglass brick and sharp metal tipped tool to scratch away the black pigment, exposing the white clapboard beneath. The references for this piece is from a photo I took while traveling across the Midwest. I pulled over when I saw this big bull Buffalo in the snow and admired his spirit and beauty. Prints are available through my website, www.arthawkstudio.com. This original is listed unframed.
