There's a book "The Birth of a Century: Early Color Photographs of America" that is similar. The photographer is William Henry Jackson, and they used something called the Photochrom process. But the color is introduced in the printing process; the actual photographs were still on b&w. The description of the process in the book is rather vague, but apparently it only involved one negative, and then the printers would make printing stones (similar to lithographs?) for each color. Guess you couldn't call it a true color photo, but a lot of the pictures in the book are very interesting.
