Diekirch, Luxembourg

From the town of Diekirch in Luxembourg. The stamp on the right is from a miniature sheet commemorating the 80th anniversary of the “Fédération des Sociétés philatéliques du Grand-Duché de Luxembourg”. What's interesting about this stamp is that it is partially made from silk. The top layer of the stamp is made from very fine silk fibres (30g per meter) and it gives the stamp an interesting texture.
