A ton of color pictures from 1900-1915.

"The process used involved a camera that would take a set of three photographs. These pictures would be monochrome but each picture would be taken using a filter of a different color. When all three monochrome pictures were projected (using light which had to be specifically colored) then the original color scene could be reconstructed."
