When in 2007 I was driving through that part of the world, I saw an exit indicating this town. Curious to visit the place that I only knew from my watercolour, I decided to leave the highway.
Looking for a parking place, I found a spot in front of what appeared to be the postoffice. I remembered there were some new stamps depicting lighthouses issued the other week. I entered the postofice and bought two blocks of these stamps.
Back home I saw that one of the blocks contains an errow. The colour shifted, what is called in French "décalage de couleurs". I show the block and a detail here. I also have a detail of the stamp as it should have looked.
I consider myself lucky, a bit like winning the lottery. Nothing wrong with leaving the highway once a while, especially when in the magic Provence.
(You know: click on the pictures and you will see them much bigger, with more detail)

This is how it should have looked:
