Bangkok is shows in the upper right with some detail, including the city's canal system. Some depths in the bay of Bangkok are show via shading. This map, simply title 'The Fourth Map' was prepared to illustrate an extremely rare Meiji Era Japanese travelogue describing a voyage to Thailand or Siam.
