From a series of (otherwise) unused, aging cards, probably 1970s or earlier, onto which a Buddhist association has overprinted a seasonal greeting in Chinese, in large red characters, on the reverse.  In this series, the greeting is always the same.  To see it, go to our scan for card #20326413.  This card differs from others in the series by having elaborate and ornate artwork on the reverse, with English caption but also a very large “Bangkok in Colour” legend.  You could send it as a postcard but without much of a message.  Grade: 1
