I found this image online on the website. The description was in Dutch saying "Groepsportret met het personeel van de Imperial Bank of Persia, Teheran" which can be translated as Group portrait of the staff members of the Imperial Bank of Persia, Tehran, Persia. According to Wikipedia, the Tropenmuseum (meaning Museum of the Tropics) is an anthropological museum located in Amsterdam, the Netherlands. It has been established in 1864.
