This is the first Thai edition. The ring, medallion, and sword are actual objects embedded in pockets in the hard covers and covered with a plastic coating.
The Thai translation is unusual because "Lord of the Rings" is not translated into Thai, but simply transliterated. The titles of the constituent volumes, however, are translated. This edition shares this feature with Bengali A and Indonesian.
