This photochrome print is from “Views of People and Sites in Algeria” in the catalog of the Detroit Photographic Company. It depicts the Great Mosque (al-Djemaa al-Kabir), which Baedeker’s The Mediterranean described in 1911 as “the oldest and largest mosque in the town, founded in 1018 for believers in the Malekite ritual…. Both the mosque and its minaret, originally built by the Abdel-wadite Abû Tâkhfîn in 1322-3, have now been modernized. The entrance is by a portico in the Rue de la Marine, erected in 1837.” 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.
