A dark blue block of four stamps from Siam (Thailand) issued between 1925 and 1937.

A rare, well-preserved block of 4, unused, and without a trace of a prior hinge on the reverse.

Condition is fine. Colour is great, perforations are excellent with no flaws that I could see. Not even between each stamp.

A very nice unusual block of 4 stamps.

Please see the photos.
