Austria Post has issued World's First Porcelain stamp on 20th March 2014. The Viennese rose stamps were designed by the Vienna Porcelain Manufacturer Augarten (Wiener Porzellanmanufaktur Augarten), Europe's second porcelain manufacturer and they are claiming that it is unbreakable.
I am very thankful to Sudhan for this Odd and unique stamp. Nice addition to my Odd and Unusual stamps collection.
