Ah, that is so neat! I looked at Austria Post
www.post.at but even with the English translation could not get much of anywhere. Newbie at it.
I did find that they called this a 'Special Issue' stamp for some reason and when you look at the 'Black Print' of the stamp that they sell you can see another plane (A-320 airbus?) underneath the gold foil.
Can't get the pic to load sorry.
So I thought maybe it was an overprint hiding the mistake of showing a new plane they decided not to order after the stamp design was finalized or something of the sort.
The pic I lifted from Austria Post did not post ( ! ) so I removed it. There were stamps on it showing different prizes under the foil.
Leider Kein Preis means No Prize
Airbus A-320 means one of 5000 model planes
Flug Gewinn translates in Google as 'aerial gain' but I think it means Win Flight, as there is a 3-letter city code there.
CDG is Charles De Gaulle airport in Paris. Woo hoo!
It is neat that they have different numbers and 3-letter codes for cities under the foil. They are the codes they use at airports to say which city you are headed to and from. For luggage and freight also. Couriers use the codes. Halifax, Nova Scotia, Canada is YHZ for some reason.
I so want to scratch the darn thing now. I must put it in plastic to prevent 'accidental' scratching.
It would be neat to collect just these stamps and see if you could get all the destinations and numbers and such.
How many of these could you collect without scratching just one?
