Thailand: Cover with longest stamp in the World

I received a cover from Thailand, with longest stamp in the World. On April 1, Thailand Post issued a sheet of five stamps—the longest the world have seen, at 170 mm in length—to mark the 70th anniversary of late King Rama IX’s accession to the throne.

Each of the five stamps features the same design, which includes a series photographs of the king set against a background of luscious green fields. Nine million stamps were printed by the Thai British Security Printing Public Company.

Second stamp on cover is another stamp with King Rama IX, issued on 10.10.2010.

Thank you S .L. Liew!
