During the 1930s, London Transport’s first chief executive, Frank Pick, commissioned radical new designs for the system’s Underground stations, the famous Johnston typeface, and the iconic roundel. To mark the 75th anniversary of Pick’s passing, the London Transport Museum and the Art on the Underground program commissioned a beautiful installation in the Piccadilly Circus station. The memorial is executed in bronze, marble, enamel, and LEDs, and incorporated quotes from Pick’s own notes.
