A highlight of "Bangkok 2010" was the world's first postage stamps made from Thai silk. About 20,000 stamps had been produced, consuming nearly 5,500 meters of silk.
Thai silk has won the hearts of people worldwide for a long time and it has become one of the symbols of the country. In order to honour Her Majesty Queen Sirikit and to promote and publicsize Thai silk and silk products, Thailand Post has requested permission from Her Majesty the Queen to present then Royal Peacock brand, which certifies the high quality of Thai silk, on postage stamps and to use hand-woven silk as part of the stamps. The Royal Peacock brand will be presented in embossed foil in four colours--gold, silver, dark blue and green.
In order to add more value to the stamp collection, postage stamp sheets have been made into two types. The first type features a peacock embroidered with brown silk thread on the golden silk material; the second type presents a peacock embossed on golden foil, on a white silk material. This is the first time that this innovation has been used in an issue of postage stamps. This stampset's issue date: 04.Aug.2010.
