Antique WWI Ship Building Badge Pin

This is a super cool piece of history from World War I. This is the badge that the men wore to identify them as workers and get into the building. Very neat piece. 2.25” x 1.5” please see pics for condition overall it’s in great condition considering the age. The United States entered World War I in April 1917. Within days, the federal government created the Emergency Fleet Corporation (EFC) to construct a fleet of merchant ships. The EFC hired the American International Shipbuilding Corporation to build and operate the largest shipyard in the world: Hog Island, near Philadelphia. This badge identified the wearer as a member of the World War I Hog Island shipbuilding team.
