Issued in 1964 to commemorate the 400th anniversary of Michelangelo Buonarroti’s death, this elegant Vatican City pair showcases two of his masterful frescoes from the Sistine Chapel ceiling. The L.30 stamp depicts the Delphic Sibyl, one of the five prophetic women painted by Michelangelo, while the L.150 stamp portrays the Prophet Joel, distinguished by his contemplative expression and dynamic pose. Both designs capture the sculptural quality and dramatic tension characteristic of Michelangelo’s art, celebrating the genius who defined the High Renaissance.
