Staff Dutch East-Indies Commercial Bank 1919/20

The staff of the Hong Kong agency of the Dutch East-Indies Commercial Bank (Nederlandsch-Indische Handelsbank). My grandfather Pieter Marks (1893-1981; he's somewhat in the middle of the front row) was employed there twice, the last time ca. 1923-1928. He also worked for the bank's agency in Shanghai. This picture as taken (in a studio I presume) around 1919 or so (my grandfather left from the Netherlands for his first assignment in the East in 1915)
