Colored postcard of the capital of the Ottoman Empire was printed in the late 19th century using the process photochrome (Photochrom).

This variant of chromolithography was invented in the 1880’s by Hans Jakob Schmidt, a Swiss employee of the printing company “Orell Gessner Füssli”. The method provided for the creation of lithographic stone from a negative image.
