On 30 April 1967, Pat Lighthill, a supervisor of the Expo 67 British Pavilion in Montreal, wrote to Robin Duke of the British Council:
‘Expo has opened and is a wow. Crowds are vast and the inside of the Pavilion on Saturday afternoon was like the underground at its worst’ (BW20/13)
And Pat was not alone in being ‘wowed’: the press reaction was ecstatic. When the Queen visited Montreal on 3 July 1967, Jonathan Aitken in the Evening Standard proclaimed ‘EXPOMANIA!’ So what was Expo 67 and why did the British contribution make such a massive impact?
