Royal Mail will release an issue on the London Underground on January 9, 2013.

The issue date coincides with the precise anniversary in 1863 of the first part of what was to become London’s Underground: the steam-driven Metropolitan Railway running between Paddington Station and Farringdon Street via King’s Cross.

The Metropolitan Railway features on the first of two 2nd class stamps, while the other shows railway workers, or Navvies as they were commonly known, excavating a tube tunnel.

Edwardian commuters travelling in from the suburbs are depicted on one of the 1st class pair of stamps, while the other features the Piccadilly Line’s Boston Manor, an example of many art deco stations built in the 1920s and 30s.
Classic rolling stock travelling on the tube’s ‘deep cut’ lines in 1938 and Sir Norman Foster’s Canary Wharf Station in 1999 make up the £1.28p pair.

The four-stamp miniature sheet features 12 classic London Underground posters across four long-format stamps.
Posters include two by stamp designer Abram Games, A Train Every 90 Seconds (1937) and London Zoo (1976).
