Westerners find it both amusing and sometimes inconvenient that the Thai language cannot be transliterated exactly into “western” alphabets.  This unused card is a perfect example.  Yes, it’s the Temple of the Emerald Buddha — no problem there.  But on the front it’s spelled as “Wat Phra Keo” and on the reverse it’s “Wat Phra Keaw”.   Just a little oddity on a classic Bangkok postcard.  Grade: 1
