This Belgian stamp, issued in 1990, commemorates the Ros Beiaard procession in Dendermonde, a traditional folkloric event held every ten years. The stamp features the legendary giant wooden horse, the Ros Beiaard, with the Four Sons of Aymon mounted atop it, dressed in medieval-style armor. Colorful streamers and a festive backdrop evoke the celebratory spirit of the parade. A UNESCO-recognized masterpiece of oral and intangible heritage, this festival is a significant cultural symbol of the Flanders region.
