The Dutch East Indies company put on a Colonial World Fair of objects and photographs collected in its colonies. There is now a website where many of these photographs are available for research.
These photos can be searched at a site called The Memory of the Netherlands here. The keyword 'tea' will bring up 15 photos, one of which is shown here. There is one other photo of a man in a tea field, and 3 photos of tea in processing or packaging. More interesting photos are forthcoming if the Dutch word for tea(thee) is input. There are 275 results for Dutch, I tried French, but I didn't put the diacritical over the 'e', so the results weren't useful.
