A photograph of a woman at an exhibition stand at the Radiolympia show at Olympia, London, taken by George Woodbine for the Daily Herald newspaper on 18 August 1932. Two giant Cosor valves appear prominently at the front of the stand. Cosor were leaders in the production of valves and radio sets, both completed and in kit form. Cosor went on to make television receivers, and during World War Two helped to develop radar. Before the invention of printed circuits, electronic devices such as radios relied on valve technology, or vacuum tubes, to function. This photograph has been selected from the Daily Herald Archive, a collection of over three million photographs. The archive holds work of international, national and local importance by both staff and agency photographers.
