This antiqued parchment document is a one large page poster sized replica of the original hand written Constitution of the United States. The Constitution of the United States established America's national government and fundamental laws, and guaranteed certain basic rights for its citizens. It was signed on September 17, 1787, by delegates to the Constitutional Convention in Philadelphia. The Constitution is the supreme law of the United States. Empowered with the sovereign authority of the people by the framers and the consent of the legislatures of the states, it is the source of all government powers, and also provides important limitations on the government that protect the fundamental rights of United States citizens.
