Italy – San Marino joint stamp issue: 550th Anniversary of the Borders Determination

June 8th, 2013

The Joint stamp issue by San Marino and Italy designed by Marco Biordi celebrates the "Patti di Fossombrone" (Pacts of Fossombrone) (1463) by which San Marino obtained the castles of Montegiardino, Fiorentino, Serravalle and subsequently also Faetano and became the territory we see nowadays.

The souvenir sheet with four values shows the papal bull by which His Holiness Pius II ratified the clauses of the previous agreements between San Marino and the papal legate Cardinal.
