1970s Frank Colson Polychromed Terracotta Mask. Frank Colson is known for sculpture in clay, bronze, and mixed media. His signature pieces include flat, mask-like wall pieces and metamorphic representational animals. At Scripps College, Colson studied with Paul Soldner and Richard Petterson. Colson was inspired by world travels. His own term for his artistic style was “neo-primitive.” Before settling down in Sarasota he had lived in 67 countries and had always found himself drawn to “native artists, particularly those working in clay[1].” Throughout his artistic career Colson worked with clay and bronze and was constantly interested in trying different techniques and materials. Colson claimed his desire to master so many different media came from his strong sense of adventure and the “desire to immerse himself in the mechanical and manual arts. Size: 12 x 12 #1581
