Attractive color-lithographed map of New England, issued by the Boston and Maine Rail Road to promote regional tourist travel to the White Mountains.
The map extends from New York City in the far southwest to the New Hampshire border with Canada in the north.
The "White Mountain Region" is shaded green, while the railroad routes are red, with stops marked as white dots.
OCLC lists two entries for the map, at the Hagley Museum & Library and the University of Chicago. The OCLC date is "1930s", which feels a little late but might be correct.
