    EXTREMELY RARE COLOR BONNAUDTYPE IMAGE OF LILLIE LANGTRY. In 1879, J. B. Germeuil-Bonnaud developed an incredibly complicated process by which color photography could be achieved by exposing a plate coated with treacle, sodium borate and potassium bichromate under an ordinary positive transparency. Portions of the image were then altered selectively and dried in an oven. Three prints from three negatives were created representing the three primary colors - red, green, and blue - which were then dusted with sensitive silver halide compounds to create the various colors. A single image was made by overlaying the three prints and using them to develop a final combination print. This astounding process did not become publicly known for nearly a decade, but by then other color reproduction processes were in the works. Suffice it to say that this "Bonnaudtype" process is exceedingly rare and almost never seen. Here, Bonnaud has created a stunning 1879 profile portrait of the famed British actress Lillie Langtry measuring 7.25" x 11.25". Exquisite imagery combined with the rarest of all color photography processes make this portrait a one-of-a-kind collector's sensation. The print has been affixed to Bonnaud's slightly larger black photographer's mount with gilt edging and lettering. Pinholes at each corner of the mount are the only detraction from this amazing and incredibly rare item.
