This 0.60 franc commemorative stamp from France, issued in 1968, marks the 650th anniversary of the Enclave des Papes (“Enclave of the Popes”). The stamp, designed by André Spitz, depicts the historic moment when the region of Valréas and neighboring towns — Grillon, Richerenches, and Visan — became possessions of the Papacy during the Avignon period. The detailed engraving shows a papal figure receiving homage, with a map of the enclave to the right. The design honors the centuries-long link between the area and the Papal States before its eventual return to France during the Revolution.
