"Till the late 19th century, the native mountain people of Northern Luzon were relatively unknown to much of the world. Shrouded in mystery, and protected by cloud-topped mountains, they lived far from mainstream lowland Christian civilization of the Philippines... In the 1880's, however, the mountain tribes of the Philippines had attracted attention from German scientific circles ever since specimens of their woodcarving, weaving and iron work appeared in the Amsterdam Colonial Exposition in 1883." - Ambeth Ocampo, NHI Chairman (2008)
The National Historical Institute (NHI) - now National Historical Commission of the Philippines (NHCP), acquired an album of Meyer published in 1891. The photos were reprinted and was published in 2008. Below are a few scanned pages of the book entitled "Tipos Filipinos" or translated simply, "Types of Filipinos."
