A bronze-toned photograph of one of Ireland's most revered cultural treasures — the Brian Boru Harp, the oldest surviving Irish harp, its carved willow soundbox and intricately knotwork-engraved brass neck captured in crisp studio-lit detail against a clean white ground. Dating to the 14th or 15th century and housed at Trinity College Dublin, this instrument became the model for the Irish national symbol and the emblem on Irish coinage and the Guinness label. The postcard was printed in Ireland and carries the divided-back undivided-style layout consistent with early 20th-century Irish souvenir cards — never posted, never written on, preserved in exceptional condition for a collector of Irish antiquities, music history, or Celtic ephemera.
