Where in London can you find this sculpture?
I posted this picture on Twitter at lunchtime today with that very question. I've had a couple of re-tweets but no correct answers so wonder if I should give you a clue.
Clue - I found this sculpture on one of the tube strike days when walking between London Bridge and Westminster Bridge on the south side of the river.
Does that help?
First person to respond with the correct answer - either on Twitter, Facebook or in the comments below will win 2 places on one of my walks. I am planning to add some walks into my calendar very soon so watch this space!
