Cooper, who is commissioned for both public and private works, has had his art exhibited and is collected privately throughout the country. One of his best-known pieces, however, can be found in Center City Park in Greensboro, North Carolina.
Libation, the centerpiece of the park, is an 8-foot-6-inch bronze fountain comprised of two containers continuously brimming over. While his larger works are primarily iron, Cooper works in several different type of metals.
