The Pennsylvania State flag classically symbolizes the ideals, commerce and strength of the Commonwealth of Pennsylvania, also known as the “Keystone State.” The Pennsylvania flag consists of the state Coat of Arms embroidered on a blue field. Draft horses appear on both sides and an American eagle sits atop the shield. The shield contains symbols of Pennsylvania’s strength. A ship carries commerce to all parts of the world. A clay-red plough signifies the state’s natural resources. Three golden sheaves of wheat represent Pennsylvania’s fertile fields and its wealth of human thought and action. An olive branch and a cornstalk symbolize peace and success. The state motto: “Virtue, Liberty, and Independence” is elegantly written on a red ribbon below the shield.
