I love (the) London (Tube)

I was back in London for a very quick visit. In and Out. No time to see anyone.  That is my work life nowadays. 

Even though rush took over,  I had to stop and take pictures of these images below.

They were on a big wall outside Southwark station: the selected creative photos made by Londoners who celebrate the London´s underground iconic symbol (the red loop and a crossing blue line). 

Arguably it is most famous underground sign in the world...
