London: Yesterday and today, features specially designed local history posters at Leicester Square, St Paul's and Westminster Underground stations. Posters on the new themes have just been installed.

The Leicester Square display looks at the development of Chinatown from the early days of the 20th century. It features the forerunner of the now familiar Chinese restaurants - a 1920's Chinese eating house with the crockery and cutlery needed to enjoy what then must have seemed a very exotic meal indeed.

At St Paul's the display focuses on the traders of Cheapside over the past century. It also highlights the growth of modern shopping in the area to meet the needs of today's prosperous City workers. One of the illustrations features a "CB Cyclist Corset", a far cry from today's lycra shorts.

Westminster's display looks back at the celebration of the Queen's Coronation in 1953. Pictures of a Coronation mug and a souvenir model of the State Coach are displayed alongside contemporary photographs by Henry Grant of a children's Coronation party and spectators viewing the Coronation procession. This display offers a nostalgic glimpse of history that is in the living memory of many travellers.

London: Yesterday and Today will offer a constantly changing view of London's history throughout the year. New displays are planned for the autumn and the programme could expand to reveal the past of more stations.
