London Transport has always sought out the very best in design, whether superb art deco tube stations, it's elegant Johnston typeface or Harry Beck's tube map. This pursuit of excellence extends to the design of the moquette fabric it uses. In conjunction with the London Transport Museum, which has the definitive London Transport moquette archive, Andrew Martin has written a delightful, surprising and covetable guide to all these patterns, from the first horse bus to the latest tube train.
