The first postage stamps issued by the papacy were issued under Pius IX in 1852 for the Roman States. They were inscribed "Francobollo Postale" and included a design featuring the keys of St. Peter and the papal tiara. That papal postal system ended in 1870, termined by the Italian authorities. With the signing of the Lateran Pact in 1929, the Vatican once again had the right to issue its own coins and postage stamps. The first stamps issued in 1929 featured a similar design to those of 1852, with St. Peter's keys and the papal tiara. Stamp designs since often commemorate saints and other important historical figures, Church councils and other events, popes and their travels, and artwork. Most years had a special Christmas design. There are stamps issued in honor of all eight popes since 1929, as well as Sede Vacante stamps for every period between popes. In 2000, Pope John Paul II issued the first automat-generated stamps.
