A friend of mine was generous enough to take a picture of one of the jewels in his collection, so I can now present the reverse Madonna, one of the greatest Hungarian stamp rarities.
Less than 20 copies are known to exist of this very spectacular misprint. It is therefore one of the rarest and most spectacular misprints of philately in the world. In my opinion, its true rarity is not reflected in its current market price of a few tens of thousands of euros.
