I just figured this out, too - apparently, in the UK, they use pictogram "Exit" signs, instead of the word itself (https://en.wikipedia.org/wiki/Exit_sign). Look at the match:
Is that creepy, or what?!
So I took it further, and did an overlay. I count 16 alignment match-points/lines (I included the heel, what the hell, it's so close). The olympic rings even give the guy a neck in the correct place. And look at the spacing alignments for the upside-down ascenders in the "london"! LOL!
