This is the design for platform murals at Tottenham Hale station on the Victoria Line on the London Underground system which opened in 1968. Thousands pass it every day without knowing it is the work of Edward Bawden. During the Covid-19 pandemic we used it to remind visitors to keep two metres apart.
