1875 Meiji 8 Japanese Map of Bangkok, Thailand (Siam)

A scarce Meiji 8, 1875 Japanese issue map of the Chao Phraya River from the Bay of Bangkok to the city of Bangkok. Bangkok is depicted on the upper right with some detail, including the city's canal system. Some depths in the Bay of Bangkok are included via shading. This map, simply titled 'The Fourth Map' was prepared to illustrate an extremely rare Meiji Era Japanese travelogue describing a voyage to Thailand or Siam. We have identified only two other examples of this map located in the archives of the Waseda University Library, Tokyo and the Kyoto University Library, Kyoto.
