Singapore released its largest stamp this October with a $2 issue showing the Marina Bay Central Business District.
Measuring 163.2 millimetres wide, the stamp offers a panoramic view of the island city-state’s 360-hectare downtown area, which is the result of nearly 30 years of land reclamation.
Despite its massive size, the new issue is smaller than Mongolia’s 2004 “Peace Mandala” stamp, which measures 185 millimetres across and is believed to be the world’s largest stamp released by a postal administration for use on mail.
Thailand’s 2016 stamp marking the 70th anniversary of King Bhumibol Adulyadej’s accession to the throne is believed to be a close second, measuring 170 millimetres wide.
Canada’s largest stamp – the 2010 $10 blue whale (Scott #2405) – measures 128 millimetres across.
