These postcards of the capital (then known as Constantinople) of the Ottoman Empire at the close of the 19th century were produced using the Photochrom process. The technique applies layers of artificial color to a black and white image with surprisingly realistic results.
These vibrant snapshots of daily life in America in the 1900s were popular Photochrome postcards – created by blending photography and early colour printing techniques. From the Lucky Strike billboards to the Chicago railway track that opened up travel to all, these tourist souvenirs were printed in their millions each year and offer a detailed journey into the past. They were taken in a decade when the United States was on the cusp of its Industrial Revolution bouncing back from the depression of the 1890s. Immigration was beginning to boom and while the country was still largely rural, pioneers such as JP Morgan and Andrew Carnegie were starting to shape history.
