I am looking for a railway map of the United States published in the 1930s. We do have this map (https://www.loc.gov/item/2006627696/) but it was published in 1923. I am not sure whether the National Railway Publication Company published a similar large map in the 1930s or not. If they have published such a map, do any of you have this map?
