ok, here is the list of post offices in AT where you get the stamp (not sure about the one in 1210 Vienna):
https://imgur.com/suqgGo9The ink stamp is always the same (1 ink for all 4 stamps) but this time also shows the ZIP code and city where it was stamped.
do I understand it correctly that in these 4 post offices in Austria, on this specific date you can ...
- buy this ink stamp?
or
- get a letter/postcard stamped with this ink stamp?
