This photochrome print is from “Views of People and Sites in Algeria” in the catalog of the Detroit Photographic Company. It depicts the Cathedral of St. Philippe in Algiers, originally the Ketchaoua mosque, which had been converted to a Christian place of worship under the French occupation. The structure was rededicated as a mosque following Algeria’s independence in 1962. 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.
