This ad card was mailed to Hong Kong residents (using Hongkong Post’s English-language Circular Service postage imprint) in late 2018 for a contest linked with the opening of Istanbul’s new airport.  The point is to write your New Year’s wish and post the card back to a local (HK) address for a chance of winning a trip.  But that’s not all!  There are terms and conditions!  Including one that will winnow out quite a few potential entrants.  Above all, be “stylish”.  Grade: 1
