"An Elaborate Collection of Colored Views, Published with the Approval of George R Davis, Director General of the Columbian Exposition, Comprising Illustrations of the Greatest Features of the World's Columbian Exposition and Midway Plaisance: Architectural, Artistic, Historical, Scenic, and Ethnological. The Magnificant Water and Landscape Effects and Charming Vistas Made Realistic by Authentic Reproduction in All of the Colors of Nature and Art, Under the DIrection of the Celebrated Landscape Artist John R Key.

My understanding is that photographs of the time were still black-and-white, and an artist later re-colored the B&W photos for publication.
