The recent BBC series The Thirties in Colour showed footage of London before the bombing of the 1940s destroyed the continuity of building that had previously existed.
One shot showed a street more or less unchanged in its architectural and street furniture essentials from Edwardian times – the exception being Hans Schleger's request bus stop, designed 1935–7. In the shot in question, the extraordinary modernist simplicity of this sign, and its startling use of colour, shone out in contrast to the rather fusty surroundings.
(Some idea of the effect can be seen in the photograph on page 97 of Pat Schleger’s book about her husband's work; again, the only ‘modern’ thing in the photograph is the typography.)
