This black and white photograph by Carl J. Kleingrothe, titled "Koffie-etablissement 'Greahan' (boven) en koffiesorteersters in een schuur (onder) op Sumatra," shows a coffee plantation in Sumatra. The top image depicts a large building, likely a processing facility, situated on a hillside amidst lush greenery. The bottom image shows a group of women working in a warehouse sorting coffee beans. Taken before 1898, this photo offers a glimpse into the labor-intensive coffee production process in Sumatra during the colonial era.
