From the website of Mr. Foppoli:
Marco Foppoli also produces ecclesiastical coats of arms and had, for a number of years, enjoyed the honour of Mons. Bruno B. Heim, Papal Nuncio and the celebrated pontificial heraldist who produced the official armorial bearing for Popes John XXIII, Paul VI, John Paul I and John Paul II in additons to numerous coats of arms for prelates. Mons. Heim described Marco Foppoli as his "pupil in Italy" to whom he had passed on a part of his huge experience in church heraldry.
