UPDATE: Chinese Laborers Postcard

Last July 7th, I had an entry entitled "Chinese Laborers Postcard." I was browsing the Filipiniana book "100 Events that Shaped the Philippines" when I noticed on page 165 that the picture and my postcard are the same!
The caption on the book reads "Sangleys delivering tobacco to factories." Sangley is an archaic term used to describe and classify a person of pure Chinese ancestry. Now I know what they were carrying, but still have no clue what's the name of the church in the background .
