The flag of the US State of Pennsylvania consists of the state’s coat of arms on a blue field. The Pennsylvania coat of arms consists of a shield flanked by two horses and a bald eagle perched upon it. Upon the shield is a ship, a plough, and three sheaves of wheat. The ship represents the state’s commerce, the plough represents the state’s resources, and the wheat represents the state’s fertile fields. Below the shield is a olive branch and corn stalk, symbols of peace and prosperity. This flag was adopted on April 24th, 1907.
