This miniature sheet is from a postcard that I sent to myself from my first business trip back in 2015.
This special edition was issued back in 1998. According to wikipedia, this Air Traffic Control (ATC) Tower was the tallest in the world when it was built. It monitors two runways for Kuala Lumpur International Airport (main and also referred as KLIA1) and KLIA2 (domestic). Currently this tower is only 3rd highest in the world. It has been overtaken by another tower monitoring a 3rd runway for KLIA2 and that in Suvarnabhumi International Airport - Bangkok.
