Pos Malaysia released an overprint on miniature sheet for the stamp exhibition Phila Nippon 11'. The stamp exhibition was held in Japan in August 2011. The overprint was done on the KTM miniature sheet of that issued in 2010 (click here to see this original miniature sheet). This KTM miniature sheet was also overprinted previously for stamp exhibition Bangkok 2010 (click here to see this Bangkok 2010 overprint). So, this is the first time Pos Malaysia made overprint twice on the same miniature sheet.
