Kinder is a candy brand owned by the Italian Ferraro company. They produced promo items to go in the german Surprise Eggs product, very much like McDonalds did with Happy Meal Promo's here in the USA.  

This car is a very rare find, it's the least produced and hardest to locate of all the Citroen 2CV's that Kinder produced as promos for inside the candy eggs. You will find a nicer example of this color, if you could find one at all! (Approx 1:72 Scale)
