Negaraku harmoni
Card jointly issued by the Post Office and a local TV station, this roughly means “my nation of harmony” and has a pre-printed stamp. Two are available. One was mailed in the mid-1990s and had been significantly folded (Grade: 4, $2) and the other was mailed in 1993 with an extra stamp and airmail sticker, lacking any postmark but with orange barcoding through the two stamps (Grade: 4, $2).
