This striking provisional issue comes from the turbulent 1919 period following the fall of the Austro-Hungarian Empire. The base stamp is the ornate green-framed 20 fillér definitive, here boldly overprinted “Köztársaság” (“Republic”) in black to mark the new republican authority. Such overprints were applied in haste, resulting in numerous variations prized by specialists. This example shows a clean red numeral and sharp overprint, making it an attractive addition to any collection of Hungarian transitional issues, post-WWI political shifts, or overprint studies.
