The revolutionary photocrome process was unveiled at the Universal Exhibition in Paris in 1900. This unique new approach permitted the first-ever colour images of the worlds most famous sites and landmarks, and elicited unprecedented admiration on both sides of the Atlantic. The process remained in vogue until the 1920s, before being superseded by more modern colour photography methods. This book offers a richly varied collection of over 300 such images from 47 countries. They continue to astonish not only by virtue of their freshness and naivete, but also because of their remarkable realism. As such, they represent a mute yet vivid testament to a forgotten era.
