Colour on the Thames
Colours on the Thames (1935)
A rare colour snapshot of the Thames and London in the 1930s, using the Gasparcolor system.
Gasparcolor was a colour film system, developed in 1933 by the Hungarian chemist Dr. Bela Gaspar. It used a subtractive 3-color process on a single film strip, one of the earliest to do so. During the 1930s and 1940s, it was used primarily in animation. (Wikipedia)
