Harry Beck’s first sketch of a diagonal Victoria Line
This unique manuscript sketch by Harry Beck, the designer of the iconic London Tube Map, shows an early attempt to add the Victoria Line (still under construction at the time) to his Underground diagram. His elegant and ingenious proposal introduces the Victoria line as a clean diagonal running from northeast to southwest. This sketch focuses on the most complex section of the map: Highbury & Islington to Victoria.
