I found this Singapore/Malaya stamp in one of Penrose Annual publication in 1957. Isn’t it interesting. Makes me wonder how many new generation in Malaysia knows this stamp. Yet I found this stamp published in a book that has been published nearly 41 years in United Kingdom. In this articles the discussion is about the photogravure technique and process. Apparently it was the lastest printing technique at that time. There are others sample and discussion in these book, health which I intend to upload soon.
