Hi, Dimasalang. Do you have the name of the person who made the map and the date it was made?
There are other similar ethnographic maps made before the colonization of the Philippines by the USA. Here are a couple of samples which I would like to add, thanks to the initiation of this thread by Dimasalang.
One is attributed to Fernando Blummentrit, dated 1890. He was a respected ethnographer who wrote on the Philippines. Unfortunately, he had never visited the country
Another is by the Manila Observatory (made by locals under the supervision of Jesuit priest, Jose Algue), dated 1899. The map was turned over the Americans after the Spanish-American War. Thus, the details in the map are in Spanish, while the attribution (printed on the top left corner of the page) is "United States Coast and Geodetic Survey."
An earlier map by Pedro Murillo y Velarde, dated 1734 is somewhat "ethnographic" as it contains images on both sides of the peoples and their customs - e.g. Bisayan, Aeta, Arabs, Chinese, Japanese, Mongol, Spaniard, Armenian, etc.
It is always good to know the background of historical sources, in order to assess their value and limitations. The stories behind them are also interesting
