Deutsche Post - Schloss Neuschwanstein. The third issue of the crypto stamp brings excitement to the world of digital collecting and adds another highlight to stamp series 'historical buildings in Germany'. The new crypto stamp shows an AI-generated depiction of the ‘castle of the fairy tale king’, King Ludwig II. Neuschwanstein was opened to the public shortly after the death of King Ludwig II in 1886. The landmark is one of the most visited castles in Europe. The crypto stamp combines the physical stamp, which always has the same motif, with its digital twin (NFT) in a novel way. The NFT is available in five colors and different rarity levels: pink/gold 0,25%, pink 1,75%, blue 10%, purple 25% and yellow 63%. As with all stamps in this series, an artificial intelligence (AI) has interpreted the motif of this impressive building.
