What makes this card unusual is not so much the 1986 calendar sponsored by Lucky Strike Filter cigarettes–though you do not see a cigarette–as it is that it was used by the Malaysian Post Office to introduce a postcode system in the country. Each card has the correct code and city for the intended recipient’s area. It was delivered, but being from the Post Office itself, was of course not stamped or postmarked. Fully pre-printed in Bahasa Malaysia (the Malay language) on the reverse. Grade: 1
