Street art

Although it disturbs me to see graffiti covering walls, fences, and every available surface on the train station platforms (and the tunnels in the Metro), this I love!  The street artists of Paris are recognized for their distinctive style and themes. 
This panel is by the artist Nemo.

Oh, I checked to make certain that I am not showing this upside down!
