Who knows, there may have been a time not so long ago when Patpong accounted for the majority of overseas visits to Bangkok. But why is this card a bit more expensive? It’s because of the stamp on the back, a 1-1/4″ by 4-3/4″ massive view of one of the royal barges during the Golden Jubilee in 1996. Card was mailed in 1997 and the stamp has one legible postmark. Despite a little bit of abrasion on the reverse, this card is well worth the price. Grade: 2
