A classic World War I era Hungarian semi-postal, featuring the ornate Crown of St. Stephen keyplate in olive green, upgraded with a bold red “Hadi segély” (War Relief) overprint. The vertical surcharge increases the face value to 6 filler, raising funds for wartime aid. This issue is part of the 1914–1916 charity overprint series—highly collectible for its historical context, typographic variations, and numerous overprint settings. Clean impression, crisp red typography, and strong centering add to its desirability for specialists of Austro-Hungarian postal history.
