A family were in my way in the waiting room. After they noticed me and moved, I explained the concept of Labyrinth and the mum of the family also took a photo. I then explained my challenge and I'm sure they thought I was mad...
... by utter coincidence our carriage position was right by this one, so I got back on the same train and "mum" took a photo through the window. They were heading to Oxford Circus - I wonder how many more they've noticed now that they know.

I went astray looking for this one. I thought it was at the top of the lifts near the Northern Line plaforms. I had to use the exit next to the shopping centre and go across to the Leslie Green designed "Bakerloo" station.
