Category:20th-century maps of New England

Maps created between 1900 and 1999, showing multiple or all of the following states, may be sorted directly into this category: Maine, New Hampshire, Vermont, Massachussetts, Connecticut, Rhode Island. Maps that show just two or less of the New England states, should be sorted into the categories of the respective states.
Maps that also show large parts or all of New York, New Jersey and Pennsylvania, should be sorted into "Maps of the Northeastern United States" instead.
