On the occasion of the issue of a stamp dedicated to Jorge Juan y Santacilia, Knight of Malta, on the 250th anniversary of his death, the Poste Magistrali counter located inside the Magistral Palace in Rome, with public entrance from Via delle Carrozze 79, will use a special postmark on June 23 2023.

The postmark, created by Giancarlo Federico, reproduces the portrait of Jorge Juan y Santacilia, Knight of Malta, Spanish mathematician, scientist and naval officer, housed at the Naval Museum in Madrid. The postmark is completed by the inscriptions “SOVRANO MILITARE ORDINE DI MALTA”, “POSTE MAGISTRALI” and “GIORNO DI EMISSIONE”, “JORGE JUAN y SANTACILIA” and the date “23.VI.2023”.

Items for reposting, individually franked by the sender with stamps belonging to the relevant set, must reach the Poste Magistrali office by 23 August 2023. A suitable self-addressed envelope, bearing the Order of Malta stamps corresponding to the ordinary (Posta4) or priority (Posta1) postal rate in force in Italy, must be enclosed for the postmarked items to be returned under cover. For any return by registered mail, please contact Poste Magistrali in advance.

Items to be returned uncovered must reach Poste Magistrali by 7 July 2023 and must be individually marked as “Corrispondenza filatelica” (Philatelic correspondence) on the address side in indelible ink. Should this indication be missing, it will be applied by Poste Magistrali.
