This is a beautiful Souvenir Sheet depicting fireworks, jointly issued by Austria and Hong Kong. The Austrian stamp shows the Prater Ferris Wheel in Vienna, and the Hong Kong stamp shows fireworks over Hong Kong Harbor. Both stamps have Swarovski crystals attached to the stamps. Scott catalog lists an Austria sheet of 2 as #2060, and a Hong Kong sheet of 2 as #1208, but it does not list this sheet, with one stamp from Austria and one from Hong Kong. They are in a cardboard presentation folder with two holes cut out to display the stamps, which is shown, but the sheets themselves look exactly like the folder. It's Post Office fresh, F/VF, mint never hinged. While you will see both the Austrian and Hong Kong sheets on the market, it is RARE to see this joint sheet. We have just four of these available, so don't delay.
