The latest tube map cover has just been revealed

Since 2004, TfL has been commissioning artists to create covers for its pocket tube maps. Y'know, those ones you tend to see in the hands of baffled tourists who seem convinced Madam Tussauds is in Upminster. Now it's former Turner Prize nominee Gillian Carnegie's turn. She's created the twenty-fifth cover, and it's just been revealed. 

Carnegie is best known as a painter, but for her commission she's created a pastel drawing. It's based around one of those things that Metropolitan line commuters see every day, but probably never actually look at closely: the fabric that covers the seats. In a clever twist, Carnegie used the colour palette from a 1916 Metropolitan Railway timetable cover, which she dug out of the London Transport Museum's archive.

Here are the full 25 commissions in all their colourful glory:

In other tube news, the night tube is definitely launching on the Piccadilly line this weekend.

And you'll soon be able to buy tube-inspired chocolate bars.
