The Library of Congress has archived thousands of illustrations and photographs online. In browsing through some of the collections, I came across the above image taken in Baghdad in 1872, when the city was under Ottoman control. The photographer was Pascal S├ębah. According to the description, the three individuals shown are: (1): Arab of the Chammar (Shammar) tribe; (2): Arab of the Zobeid tribe; and (3): married Muslim woman of Baghdad.
