This unused card is strange for at least two reasons.  First, the extensive and florid caption does not say where the tower is (was).  And there’s your clue to reason #2:  though only built in 1982, the tower was demolished in 2017.   Seems as though the concrete was deteriorating, and anyway there were plans for something different.  As far as we know now, the USA and Canada are still at peace, though.  Grade: 1
