Just took a peek... early 1900's London... quite amusing, but THEN....
I spotted this set at the bottom...
100 year old COLOUR photo's!
Pre-War Tzarist Russia. Absolutely incredible. Peeking at a couple of them, I suspect this is the early, 'seperation' method, taking three black & white plates, with red, green and blue filters; which were extremely difficult to print and usually produced quite flat and artificial colours. But these seem to have been made from the original negative seperations and digitally recombined, and are superb!
