Moquette is the durable upholstery fabric used on public transport across the world. This is a sample of the 'Shield' design, with a repeating geometric pattern of interlocked diamond and lozenge shapes in red and light green on a dark green ground. It was designed by Enid Marx, one of three artists that Christian Barman, London Transport's Publicity Officer, commissioned to create new designs for trains and buses during the 1930s. This moquette was widely used on the refurbishment of the 1938 Tube stock from 1949. It was used with green leather armrests on cars for the Bakerloo, Northern and District lines.
