On the occasion of the Solemnity of Christmas 2025, the Postal and Philatelic Service of the Governorate of Vatican City State will issue a pair of commemorative envelopes, also available inside a dedicated limited-edition folder.
On 11 December, exactly one hundred years after its foundation, the unveiling ceremony of the two commemorative stamps jointly issued by the Vatican City State and the Grand Duchy of Luxembourg took place at the Pontifical Institute of Christian Archaeology.
