This Christmas card features Duccio's Nativity illustration.  It was originally the center panel of his triptych with the prophets Isaiah and Ezekiel flanking on both sides.

Text inside: 
“The angels sing and the archangels blend their voices in harmony. The Cherubim hymn their joyful praise. The Seraphim exalt Christ’s glory. All join to praise this holy feast, beholding the Godhead here on earth and man in heaven.”   – St. John Chrysostom
