Issued by France in 1973, this 0.50 franc commemorative celebrates the Musée Postal and the Maison de la Poste et de la Philatélie in Paris. The design features the building’s striking modern façade, with geometric relief panels rendered in fine engraved detail. A. Chatelin and R. Juvin’s craftsmanship highlights the architectural innovation that housed France’s postal heritage collections. For collectors, this stamp is valued for its artistic engraving, postal-thematic relevance, and its link to the evolution of philatelic museums in France.
