Issued by Romania on 8 June 1938, this green semi-postal stamp (denomination 2 Lei + 2 Lei surcharge) features a portrait of Constantin Brâncoveanu (1688–1714), Prince of Wallachia, who is remembered as a national hero and martyr. The design includes his name and dates within an oval frame, with the word Straja Țării (Guardian of the Country) above. Printed by Fabrica de Timbre, the issue raised funds through the surcharge for youth and national defense causes. This stamp is part of the 1938 patriotic semi-postal series honoring Romanian historical figures.
