Monaco’s stamp office scheduled a €1.52 stamp for 5 November 2026 marking the 50th issue of Annales monégasques, the historical journal of the Prince’s Palace Archives. The journal began in 1977 and revived a tradition of research publications associated with the reigns of Charles III, Albert I and Louis II. Its articles bring together researchers working on different periods and subjects in Monaco’s history.

The stamp depicts the journal cover, with a black-and-white wedding photograph credited to Fausto Picedi through the Palace Archives. The red lettering identifies the publication and its milestone issue. The vertical stamp measures 30 × 40.85 mm and was printed by offset. It was scheduled to go on sale through the stamp office, Monaco’s postal and philatelic outlets and the Carré d’Encre in Paris.
