 Similar figures are repeated at the uppermost corners of the central tower, just below the sloping roof.About above street level, representations of bulls protrude directly from the limestone cladding on the building's north side and to a lesser degree on the east side, a reference to a bull market.The central structure is capped by a 6,500 pound, tall aluminum statue by sculptor John H. Storrs of the Roman goddess of grain, Ceres, holding a sheaf of wheat in the left hand and a bag of corn in the right hand, as a nod to the exchange's heritage as a commodities market.
