• 8th Series RAMA IX

    The stamps of the 8th definitive series of RAMA IX, King Bhumibol Aduljadey 1927-2016, come from 6 different printing houses, each with up to 6 print runs.
    The different print runs of the individual printing companies can only be recognized by the "edge markings" of the stamp sheets.
    Since these distinctions are a small science in themselves, we limit ourselves to the obvious differences such as "plates" and perforations.
