The Great Seal of the Commonwealth of Pennsylvania is the state seal for the U.S. state of Pennsylvania. Unlike most state seals, it has an obverse and a reverse.
The obverse of the seal has a central image of a shield containing a ship under full sail, a plow, and three sheaves of wheat. These symbols represent the importance of commerce, labor, perseverance, and agriculture to the state's economy, as well as several of its geographic components (Philadelphia represented by the ship, for example). On either side of the shield are a stalk of Indian corn and an olive branch, representing the state's recognition of its past and hopes for the future. Atop the shield an eagle proudly symbolizes the state's sovereignty. The outer ring of the seal bears the words "Seal of the State of Pennsylvania," despite the state's official designation as the Commonwealth of Pennsylvania.
