Cachet: Rubber-stamped design in green or red featuring the flags of the United States and Canada. Text reads: "FIRST FLIGHT AM 4 / CHICAGO TO TORONTO". The back of the Airport Mail Facility cover also has a small blue rubber stamp featuring an American Airlines logo and the words: "TORONTO / MAY 24, 1967".
