Issued by the United Nations Postal Administration in 1979, this 31-cent stamp features a detail from a 13th-century Byzantine fresco, symbolizing the shared heritage of world art. The image shows two regal figures, likely from a medieval church mural, rendered in traditional Byzantine style with rich coloration and gold undertones. The issue was part of the U.N. series promoting the preservation of cultural monuments and artistic treasures under UNESCO initiatives. A fine example of art on stamps, it embodies the UN’s commitment to protecting global cultural heritage.
