This is a German postal stationery card from the hyperinflation era, postmarked 31 May 1923 in Königsberg (Prussia). It bears additional franking with a 10,000 Mark green Germania issue and a 50,000 Mark violet Reichspost stamp, both overprinted high-value inflation issues of the Deutsches Reich. The card is addressed to Luzern, Switzerland, making it a piece of international mail.

The handwritten message reflects the urgency of correspondence during the unstable inflation period. Cards like this are significant for collectors, as they show authentic postal use with appropriate high-value franking during one of the most turbulent monetary times in German history.

Collector’s Note: Postal history from 1923 is especially sought after, as rates changed rapidly, often daily, making such properly franked examples valuable study material.
