Two of these cards are available, each mailed in 1992.  Exceptionally, we will provide the explanation as written in the cards’ caption:  “Tak Bat-Devo, Buddhist rite held after Oak-Phansa.  It celebrates Lord Buddha’s return to earth.”  One card has four large stamps but no postmark, so (Grade: 4, $5), and the other has three different–also large–stamps and two postmarks (Grade: 1, $9).
