Notre Dame in camouflage

Obviously there are restaurations going on at the back of the Notre Dame in Paris. Often when they need to place screens, they are covered in commercials and adverts. In this case it is hardly noticable. In fact, I only saw it when I looked at the photographs behind my computer! (to explain that I have to tell you that I made this photograph in a hurry, while I was on a bicycle tour with my students, so not much time to look around :-) )
