Mailed from Christchurch Airport in New Zealand, the postmark is not quite clear enough to tell us in what year.  40-cent stamp is there.  You can see two aircraft in this picture.  One, ZK-CAV, is a Cessna 185 first registered and flown in 1961 by Rural Aviation Ltd. of New Plymouth.  The other, ZK-CHJ and also a Cessna 185, met a sad ending.  Flying for Mount Cook Airline, it was carrying four skiers plus a guide when it crashed into Tasman Glacier on 9th August 1984, killing three of the six persons on board.  The card has two perforated edges, indicating it was part of a set.  Grade: 2
