Issued by Vatican City in 1957, this commemorative stamp pair marks the return visit of Pope Pius XII to the historic Capranica College in Rome. The Latin inscription “Capranicense Collegium Revisit” records the Pope’s revisit on 21 January 1957 (XXI-I-MCMLVII). The design features a finely engraved portrait of Pope Pius XII in profile within an ornate oval frame, accompanied by Vatican heraldic symbols. Printed in two denominations—10 Lire (brown) and 100 Lire (blue)—the stamps highlight the Vatican’s tradition of honoring ecclesiastical institutions and papal events. These issues are valued by collectors of Vatican philately, papal history, and religious-themed stamps.
