Street art is big in Paris. You will be walking down the street and look up at the side of a building and see it....look at the side of a van and see it....much of it goes way beyond graffiti.
The last time we were in Paris I took this picture in the Marais district.I didn't know who the artist was and I assumed these were stencils....but they aren't. They are painted by hand by Jerome Mesnager. I find it fascinating to watch him do these.
There is a great video montage of his work on his website. It's worth checking out.
