We recently learned that most Tube stations have a unique tile pattern or mosaic created decades ago to help illiterate people find their way around the London Underground.

Times have moved on and it is likely some of those distinctive patterns just fade into the background of your daily commute.

With that in mind, here's a quiz to see if you can tell the difference between tiles on the Tube as well as a person unable to read who was born 150 years or so ago.

Some of them are quite easy, but hopefully a few of our questions might need a little working out. And maybe they'll spark an interest in taking in all your surroundings next time you head Underground.
