In around 1959 Notting Hill Tube Station underwent modernisation. The old lifts were abandoned and new escalators were installed. The passageways to the lift were sealed off. Recent work at the station has rediscovered these passageways and when they were opened they revealed a marvellous time capsule. The adverts which were on the walls the day the passageways were sealed off remained and reveal a world long since disappeared.
Workers on the renovation of London Underground's Notting Hill Gate Station were recently surprised (flabbergasted in fact) to discover a long abandoned passageway with all the original advertising posters from the 1950s still intact.
