I: THE FIRST ISSUE
The first issue stamp bore a profile portrait of King Chulalongkorn facing to the left, enclosed within an oval frame, with inscriptions of value in panels either at the top or bottom.  The first issue was intended for domestic usage only as it had only Siamese characters and numerals and included the values of 1 solot (1/2 of one att), 1 att (the local printed matter single rate), 1 sio (2 atts, the local single rate for letters), 1 sik (4 atts, the inland provincial single rate), 1 fuang (8 atts) and 1 salung (16 atts). 

1 solot block of 4


The first issue “one solot” value stamp.

When Siam introduced her own foreign postal services in July 1885, the postal stationery card rate was 4 atts, the neighbouring country foreign single rate was 8 atts and the non-neighbouring foreign single rate was 12 atts.  Since the one salung stamp was worth 16 atts which was more than 12 atts, it was devalued to 12 atts and used for the foreign single rate.  
1 salung cover
The first issue used after Siam joined the U.P.U., the earliest recorded usage on cover.
