?~1910 Fred Harvey (Detroit Publishing Co.) Postcard #79438 Main Salesroom in Hopi House, Grand Canyon, Arizona Original ~1910 postcard of the salesroom inside Hopi House. The Detroit Photographic Company was launched as a photographic publishing firm in the late 1890s by Detroit businessman William A. Livingstone, Jr., and photographer Edwin H. Husher. The company obtained the exclusive rights to use the Swiss "Photochrom" process, a technique that used lithographic stones to convert black-and-white prints to color. The process allowed the company to mass-produce color postcards that were of unusually high quality. The company changed it's name to Detroit Publishing Company in 1905 and aligned with businessman Fred Harvey to promote the American Southwest. Divided back, postally unused.
