In pictures: London Underground through history

London by Design is a permanent exhibition which celebrates the artwork and unusual designs that have adorned the walls of the underground throughout the past century.

Visitors to the London Transport Museum can now follow the creation of the iconic red, white and blue ‘bullseye’ underground sign, and view some original tube maps from the early 20th century.

Here, we bring you some of our favourite images from the exhibition…
