Austrian passport with an interesting find

A curious find! Austrian passport for a woman, issued in Vienna 1928, expired 1934. Then renewed in 1936 until 1939. But wait... this passport includes a voting card for Austria's ANSCHLUSS to the Great Reich (The annexation of Austria by NS-Germany) in 1938. The card has the same name as the woman on the passport. It was a surprise because the attached ballot card was not mentioned when I bought the document online. What a great combination and find! Austrian-German (Passport) History at its finest!
