First, have a look at this card, mailed in 1960 with stamp and full postmark.  Then (as we did), go to our favourite website for aircraft registrations and learn that this plane–whose first flight was in 1958–was involved in a crash landing off New York’s La Guardia Airport on 3rd February 1959.  Flight 320 resulted in 65 fatalities out of 73 persons on board.  These are some of the things you learn when you run a postcard website.  Grade: 2
