A subtle but vital change to the current edition of the pocket version of the London Underground map. Can you spot the difference?
That's right, they've moved a whole station. Embankment has just been nudged a little bit to the east while they work on the Northern and Bakerloo line platforms. Work will continue until November 2014. Nice adjustment keeping the map as uncluttered and lovely as ever.
The cover of the new edition is great, too…
It's called The Hole of London and is by Rachel Whiteread. You can read more about the commission at the TFL website HERE.
