Last Wednesday I got four postcards: one from Austria, one from Indonesia, one from Sweden and one from Crimea.
The card from Austria shows the Vienna Technical Museum. The Vienna Technical Museum is a museum about technical history with an emphasis on Austria's role in the technical development. It shows many working models. The foundation stone of the museum's building was laid by Emperor Franz Josef in 1909 and in 1918 the museum was opened to the public.
With a great matching stamp:
Centenary of the Vienna Technical Museum (issued 17-03-2009)
The stamp was printed with a lenticular effect.
Thank You very much Anita!
