This Crypto stamp is issued by the official Austrian Postal Service (Österreichische Post AG). This special postage stamp connects the analog world with the digital. It is not for nothing that the famous "Charging Bull" statue sits near the New York Stock Exchange on Wall Street. In the financial world, the bull is the international symbol for rising share prices, also known as a bull market in technical jargon. The international joint issue means that the Austrian version has the national flag and the edelweiss as extra design elements.
