In the image, you can see three newspaper headlines that expose some of the situations that occurred during the ratification of the United States Constitution. One of them says "Constitution Ratified in Delaware" suggesting a general acceptance of the Constitution in this State. The second says "Pennsylvania Anti-Federalist Object to Constitution" expresses an idea of opposition to federalism in Pennsylvania.
