Hundreds of postcards have been sent to give moral support to the members of Mu Pa Academy football club, who have been trapped in the Tham Luang cave in Chiang Rai’s Mae Sai district since June 23.

The Culture Ministry will hand out 3 million souvenir postcards made in nine different patterns to those visiting the Royal Crematorium and an exhibition on HM the late King Bhumibol Adulyadej’s Royal Cremation at Bangkok’s Sanam Luang ceremonial ground.
