Last week, I visited the Kunst Haus Wien museum in Vienna. The two exhibits I saw each featured Austrian stamps featuring pieces I saw in person. And lucky for me, some of the stamps were sold in the museum shop.
I don't have a working scanner, so I tried taking pictures of these. The quality isn't great, but nevertheless, I wanted to show you these stamps.
The Hundertwasser stamps have gold and silver (colored) shiny foil on them.
