King Peter I and King Alexander I

Yugoslavia · 1921 · 10d

This definitive stamp features dual portraits of King Peter I Karadjordjevic and his son and successor, King Alexander I. The design, with both monarchs facing left, symbolizes the transition of power and the continuity of the Karadjordjevic dynasty in the newly formed Kingdom of Serbs, Croats, and Slovenes.

Issued shortly after the death of King Peter I in 1921, this stamp honors the first king of the Serbs, Croats, and Slovenes while acknowledging the reign of his successor, Alexander I, who would later become the first King of Yugoslavia.
