Thailand Post on Friday launched the collective stamp which marks the 350th anniversary of the relations of the Kingdom and the Vatican.
Marking the first cooperation with the Vatican, the stamps recalled the introduction of Christianity in the Thai kingdon, when a French mission landed during King Narai the Great's reign.
The Kingdom's first Catholic church was established in the Portuguese settlement in Ayutthaya.
The stamp shows a painting of the mission. The original painting is now in France.
