This is a mystery to us.  Here’s why:  we got this pack of 100 unused cards (blank on the reverse; 2 Baht pre-printed postage on each card) in Thailand in June 2024.  The counter person said it is a contest where people can put their contact details and guess the winner, mail the card(s) and hope for the best.  However that yellow label in Thai just says “2022 World Cup Postcard” and gives the names of Thailand Post and the publisher (T.K.S. Technology Public Company).   At upper left, under those red banners it says “The champion is …” and you are to enter your guess.  Well then, anybody who doesn’t guess Argentina for 2022 is going to lose; and 2024 is not a World Cup year, so if someone wants to let us know what’s happening here, we welcome it.  The pack of cards is still sealed in its original Cello-wrap.  Grade: 1
