What shown in this card is Preah Vihear Preah Keo Morakot (literally the Holy Emerald Temple), more commonly known to tourists as the Silver Pagoda. It is located next to the Royal Palace in Phnom Penh to serve as the royal wat.
The splendid silver floored temple now houses a crystal Buddha image, and in front of it is the Maitreya Buddha image commissioned by HM King Sisowath. The Maitreya Buddha is in royal regalia with 2086 diamonds including a 25 caret diamond in the crown and a 20 caret diamond embedded in the chest (ohh mon dieu!!!). This is a black and white photograph of the Buddha image taken in 1930s.
It is notable that, the 1994 "45th Anniversary of Cambodia's Admission to UPU" 200r stamp on this maxicard is tied by the rubber postmark mentioned in my very first blog posting. The postmark is bi-colour, date in red and the rest blue. It is a mystery how this happened.
