This 1923 30 Pfennig green stamp is part of the celebrated German Inflation Series, produced during the final and most chaotic months of the Weimar hyperinflation crisis. Printed in a bold, expressionist style, the large “30” numeral fills the design with sharp decorative strokes characteristic of the Rohleder pattern issues. The stamp was typographed on inexpensive paper, a common attribute of late-inflation printings. Its strong geometric frame and Gothic “Deutsches Reich” inscription make it a classic example of emergency-period production. An essential piece for specialists studying print varieties, paper types, and period postal economics.
