This image is a photochrome. Similar to a lithograph, the individual color layers are printed separately and thus obtain their radiant colorfulness. Black-and-white photographs are used as a template; these were usually made several years before the photochrome. This photochrome process is one of the early color photography processes. Photochroms published by Photochrom Zurich, abbreviated P. Z., can often be identified by the serial number followed by the letters P. Z. and a caption in gold.
