Garden at the opera!

It's a very unexpected scene that I came across a few days ago, as I was passing by the Paris Opera (well the one we call Le Palais Garnier) ; a real "forest" growing on the front steps! I searched the web to find out more and I discovered that this was a street marketing operation to promote a new perfume for men by Guerlain (have a look at their web site, you have to be patient but it's quite impressive). I'm talking quite impressive!
