This photochrome print is from “Views of People and Sites in Algeria” in the catalog of the Detroit Photographic Company. It depicts Babel-Oued (Bab El Oued), a neighborhood of Algiers, as seen from the fortified citadel, or Casbah. The Detroit Photographic Company was launched as a photographic publishing firm in the late 1890s by Detroit businessman and publisher William A. Livingstone, Jr. and photographer and photo-publisher Edwin H. Husher. They obtained the exclusive rights to use the Swiss "Photochrom" process for converting black-and-white photographs into color images and printing them by photolithography. This process permitted the mass production of color postcards, prints, and albums for sale to the American market.
