A beautifully engraved 1974 Vatican City three-stamp set honoring St. Bonaventure (1221–1274), issued on the 700th anniversary of his death. The designs feature a portrait of the saint, a view of Balneum Regium, and a symbolic tree of life scene—each framed by ornate medieval-style patterns typical of Vatican issues of the era. This set is prized by collectors for its elegant line engraving by T. Mele, rich colors, and historical significance. A classic thematic issue combining religion, medieval art, and Vatican philatelic tradition.
