Definitely a must see if you come to Paris before June 6th. It's an exhibition called Parenthèse Végétale – (literally Vegetable Parenthesis) and it takes place in the window shops of Le Printemps, a big department store located on 64 Boulevard Haussmann (9th arrondissement). The various sceneries were composed by Mélanie Drevet et Christophe Ponceau and they stage grass, farm animals, trees, etc. A fantastic work. To know more, pay a visit to Le Printemps site.

By the way, this photo is the first one I took with the new camera I bought yesterday!
