Issued in April 1964, this Argentine commemorative stamp honors the late U.S. President John F. Kennedy following his 1963 assassination. The design features an engraved portrait of Kennedy in fine cross-hatching, rendered in dark blue against a clean white background, with his facsimile signature and denomination in red below. The vertical inscription “JOHN F. KENNEDY” appears at left, while the issuing authority “Argentina — Casa de Moneda” marks it as a product of the national mint. The minimalist yet dignified layout reflects the respect and international sympathy extended toward Kennedy across the world.
