There's a so-called 'Milchpilz', a little kiosk in the form and the colours of a fly agaric, located in Lindau, Bayern, Germany.
The first kiosk in that shape was presented at the 'large urban milk Utilities' meeting in May 1952 in Bayreuth as a "milk consumption recruiters" and later brought to Regensburg. Later on, the manufacturers 'Hermann Waldner KG' from Wangen im Allgäu trademarked the design and the name "milk mushroom". Because a milk kiosk should have a high recognition value, Anton Waldner, son of Hermann Waldner, chose at that time the distinctive shape of a fly agaric.
The mushrooms were not only sold in Germany, but across Europe also exported to Austria, Switzerland, Italy, France, Belgium and Greece.
