Collecting early Austrian postmarks (till 1918)means you have to deal with at least 10 now existing countries (if you exclude foreign offices & military post - Bosnia&Herzegovina, Turkey, Israel etc.):
Austria,
Czech Republic,
Slovakia,
Poland,
Ukraine,
Italy,
Slovenia,
Croatia,
Hungary,
Romania,
Serbia - I hope I did not forget any
