Enid Marx (1902-98),'pioneer of pattern', designed at least four classic moquettes for London Underground, following the brief that the material should ‘look fresh at all times, even after bricklayers had sat on it’. This is 'Chevron' (1938) which was used on the Piccadilly and Central lines, and illustrates her discovery that ‘the best method of ensuring the seats would look clean after a period of use was to use strongly contrasting tones and rather brilliant colour’.
