The moving image to the left is the winning soccer goal by Andreas "Andi" Herzog for Austria in 1997. The goal is a source of national pride as the Austrian national team defeated Sweden in route to their 1998 World Cup.
Now, Austrian Post is putting this moving image using lenticular printing (remember those winkie sticker when you were a kid?) on a postage stamp!
Tony Servies of Stamps of Distinction has more info:
The stamp is valid for postage, although I think it doubtful that people would use the stamp to mail something. I doubt that anyone would use such a novel stamp to mail something, preferring to hoard the stamp as a keepsake. Also, the stamp is of a large denomination, 5.45 Euros (about $8.50 US), that is would not be used for typical mail, but for packages or expedited services.
The stamp is very large. It measures 6.5 cm (2.6 inches) wide by 4.7 cm (1.9 inches) tall. With its size, denomination, and the novelty of moving images, it is sure to stand out in a stamp collection.
