Let me out!

I kinda like it when street artists use a tiny bit of the public space - hence sidewalks - to express their art. Here is a good example that can be found on several venting grids throughout Paris (I took this one close to my place). I think the signature reads "Kim" but I could not find anything on the web about a "Kim that draws on Paris sidewalks"... So, as usual, if someone knows about this artist, tell us more.
Discuss Paris art and much more in the PDP forum.
