This 1981 French commemorative honors three towering national figures—Jean Moulin, Jean Jaurès, and Victor Schoelcher—through expressive engraved portraits rendered in deep violet. Issued to mark their symbolic induction into the Panthéon on 21 May 1981, the stamp pairs their profiles with a finely detailed blue line-drawing of the Panthéon façade. Collectors value this issue for its strong historical resonance, classic French engraving style, and dual-color design. A meaningful entry in any thematic collection focused on French history, politics, or national heroes.
