Although these are postcard-sized, they are fully pre-printed on both sides and not meant to be mailed in the traditional way.  They’re ad cards.  Eight are available.  Grades: 1

Unused card TC 509.  Grade: 1

Card was never postally used, though someone has pencilled on the reverse: “1000 Buddhas Temple, Prambanan.”  Having visited Prambanan ourselves, we agree with this assessment.  Grade: 3

In the original shrink wrap and therefore unopened, a set of 12 unused aerial shots of mostly urban structures, and the Big Buddha.  Grade: 1

Card mailed in 1997, with Perak stamp and partly legible postmark. Grade: 2

No, the sky is not usually that colour.  Two cards are available.  One is unused (Grade: 1, $3).  The other was mailed in 2011 with commemorative Year of the Rabbit stamp and a full postmark, along with blue trilingual airmail sticker and minor postal creasing (Grade: 2, $5).

Mailed in 1991, this card has a Pahang stamp and almost full postmark. Front is near-perfect though back has small staining. Grade: 3

Mailed in 1991 from Negeri Sembilan, this card has the stamp and mostly readable postmark. Aging a bit, but in generally good condition. Grade: 2

Colourful and distinctive card, but mailed from Malaysia (not Thailand!) in 1989 with two stamps and Kuala Lumpur postmark, along with blue Mel Udara label.  Grade: 4

The header is as the caption reads, but then goes on to explain that either the images or the Wat were destroyed by the Burmese in 1767.  This card was mailed in 1990 with three different commemoratives and large Bangkok postmark.  Grade: 2

Four of these unused cards from 2012 are available.  Three are clean (Grades: 1, $3) and the other has some kind of printing blotch on the reverse (Grade: 3, $2).

If you are looking for a Thailand postcard with as much on it as they could fit, this is probably a good choice.  Four of these unused Thai postcards, with the six scenes individually identified on each card, are available.  Grades: 1

Unused card of this Historical Park, from 2012.  Grade: 1

Two unused cards remain, from 2012, of arguably Bangkok’s most famous structure.  Grades: 1

A card for many categories, mailed in 2012 with two different stamps and faint postmarks.  This is the “world’s largest Buddhist monument”.  Grade: 1

A card for many categories.  Yes, The Buddha is everywhere.  Unused.  Grade: 1

This is a set of five unused cards creatively sealed in what looks like a foil retort pouch (the type you can buy peanuts in).  It can’t be opened without destroying the packaging so we haven’t done that, but we could guess that some or all of the cards look like the photo in the scan.  No guarantee!  Various stickers on the back of the foil don’t affect the postcards.  The Buddha here is at Ngong Ping on Lantau Island.   Grade: 1 

The title for this item is not wrong, but slightly misleading for our purposes because the book has six postcards in it.  It’s a book inside a cardboard cover (pictured here), overall measurements 8-3/8″ x 11-1/4″.  Like many of the other items we have listed, this is a book of 16 page facings (inside covers plus seven pages) including stamp sheets, stamped envelope covers, and postcards in Maximum Card style except that none of these items have postmarks.  See 40100053B for one of the pages with a postcard.   Grade: 1
