In 1914, it could take over 40 days to travel to remote places in the world.
That year, John G. Bartholomew — Great Britain’s royal cartographer at the time — published an isochronic map showing travel times from London to various places around the globe. "Isochronic" simply means that lines (isochrones) are drawn on the map between locations that could be reached in the same amount of time. Trips range from “within 5 days journey” to “over 40 days.”
Even at first glance, it’s stunning.
