A striking Hungarian fiscal issue from the dramatic 1946 hyperinflation period, this green Magyar Posta revenue stamp bears a bold black overprint reading “500 ezer adópengő” (“500 thousand tax pengő”). The design features classic Hungarian postal emblems including the heraldic shield, horn, and scrolls, reflecting the pre-war definitive style. These overprinted fiscal denominations were produced in haste during Hungary’s currency collapse, making them important artifacts of economic history. A desirable piece for collectors of inflation-era Hungary, revenue philately, and overprint varieties.
