Charles Gesner van der Voort worked in Shanghai for Holland-China Trading Company (HCHC), which had offices in Hong Kong and Tientsin (Tianjin) also. I am preparing a book about Charles and his friends. While doing research for the book, many people contributed photos, several of which can be found on Flickr. Quite a few photos relate to Hong Kong, from the 1900s to 1930s. Please enjoy and I look forward to your comments and additional information you may have.
