Maybe we should call this “in the style of a maximum card” because it is out of the ordinary for two reasons:  first, the stamp doesn’t really match the photo exactly, and second, because it was probably not issued by the Thai post office.  But we’re not certain about that.  Nor can we quite make out the exact date on the official postmark on the front, though there is another more normal one in the postage area on the back:  Thai year 2537.  So that is what we know.  The card is unmarked otherwise.  Grade: 1
