1940 colour demonstration

The first public demonstration of John Logie Baird's 120-line system to transmit colour films on to a large screen took place at the Dominion Theatre in London on February 4 1938, with a second demonstration from Crystal Palace on February 17. He used the electronic system to produce a 600-line two by two and a half feet screen image on a colour Tele-Radiogram. This December 1940 image is of a press demonstration, and the lady beside the set is Paddy Naismith. The picture on the screen is a photograph.
