In 1977, Jane Magarigal took a series of photographs of Tube platforms, corridors and ticket halls. Her images illustrate David Long's book London Underground: Architecture, Design & History. How many stations can you identify from the photos? (Some are easy, others will take a very special kind of Tube nerd.)
More of Jane's work can be found on her website, including around 90 further images of the tube from the 1970s. All images are used with permission.
