ASEAN - Inter Asean Postmarked Postcards

This is a Thailand Post postcard which I have cancelled the Year of Pig stamp in Hatyai two years ago. I added a Malaysia 2020 World Post stamp and mailed the postcard inside an envelope to Singapore on Nov 5, 2020 with enough Singapore postage stamps that I have pasted on the postcard to have it mailed back to me. And it arrived back safely in December 9, 2020.
