The correspondence explores whether mapmakers can visually indicate doubt about position, timing, and existence of geographic features, and develops a three-part marking system to distinguish different kinds of uncertainty.","extracted_text":"LETTERS BETWEEN TWO CARTOGRAPHERS WHO NEVER MET\nOriginal epistolary fiction.

We agree the map is wrong the moment it is printed.
