Kajang Post Office is definitely one of the oldest post offices in Malaysia. It started operating in 1914. Pos Malaysia issued a set of 28 stamps on October 9, 2010 to commemorate old post offices in Malaysia. One of the stamps depicts Kajang Post Office - the old building of the Kajang Post Office. However, the building of Kajang Post Office has been renovated and the Kajang Post Office has adopted a new name Kajang 2020 Post Office. Puan Zaitun Mohammad was the post master of the Kajang Post Office (on the date 9 October 2010; she has now retired). I made a special cover to commemorate the Kajang Post Office using the one of the old post office stamps (with image of Kajang Post Office) issued on 9 October 2010. The stamp was cancelled by Kajang 2020 CDS (counter 2) on 9 October 2010, and the cover was rubber-stamped and signed by the post master Puan Zaitun. I also stamped the cover with the special first day postmark (Kajang).
I guess this cover would be very special for those into collecting special unique first day covers....
