Minerve, écusson ovale en émail de Limoges, 1555 Vidal, Leon  (French, 1833-1906)

Léon Vidal conducted successful early experiments in color collotypes in the late 1870s. — “Photochromie”, 1872 and 1874 patents using a woodburytype with chromolithographic under printings, on specially prepared Woodbury paper – the Photochromie used a series of registered lithographic colors manually separated, to produce a color image, not necessarily accurate to reality, printed over each other and then have a Woodburytype, in registration, placed over them yielding a color print. The use of metallic inks or papers, when dealing with metal objects, such as armor, created startling results. One of the drawbacks was that the prints had to be mounted inside stiff mats due to the need for them to expand and contract with atmospheric conditions. This made it nearly impossible for the process to be used in books. However there are examples of small photochromies that were glued directly to a mount. Maybe it was the size of the large prints that caused the problems. Hanson

This print is a test print from Le Trésor Artistique de la France (Treasury of French Art) a book illustrated by photographs intended to popularize the French artistic heritage and published by the Société Anonyme des Publications Périodiques (Corporation for Periodical Publications). Planning for Le Trésor began in 1876 and publishing began in 1878, and it ceased publication after its initial series, devoted to the works of the Galerie d’Apollon. Compared to similar works and considered in the context of the cultural, technological, and economic issues of the day, the evidence points to the work’s actual mission as the promotion of a new photographic process, an objective that takes precedence over the popularization of artworks. The Trésor emerges as a representative example of a type of book I propose to call the ‘livre-spécimen,’ or ‘specimen book.’ That it was never completed becomes less a sign of failure than of the changes taking place in the relations between books and photographs at the turn of the 1880s.
