Another thoughtful beauty from Agathe Keller. 2006. The stamp is a commemorative of the Fête du Timbre - The Festival of the Stamp.
Also, the caption on the stamp says "MONDE 20 g" (WORLD 20 g) - no idea what that means. Is this a stamp that can be used (could have been used) for posting in any country in the world for upto 20 grams? I must check this out sometime.
