The more research like this that we do, the more we notice little ironies and unexpected twists.  This Douglas DC-8-21 was manufactured in 1960.  The really bumpy ride started in 1978 when it went over to EgyptAir.  Finally, it was broken up in 1980.  We have two of these cards–issued by the airline–available.  The one in the scan is unused with a small smudge on the reverse (Grade: 2, $4).  The other was mailed in 1962.  It has a stamp and full US postmark, but as it was used as a QSL ham radio card, it also has call letters of that station prominently on the front (Grade: 4, $2).
