Feuerbach was an independent municipality just north of Stuttgart — it wouldn't be incorporated into the city until 1933. Like hundreds of German towns in the hyperinflationary autumn of 1923, it issued its own notgeld because Reichsbank currency was arriving too slowly and depreciating too fast to be practically useful once it got there. A two-billion-mark denomination sounds extreme, but by October 1923 it was barely adequate for daily transactions; the Rentenmark reform in November effectively ended the need for all of it within weeks of issue.

Most municipal notgeld of this type was printed on whatever stock was locally available, often on one side only. Feuerbach's issues are not among the elaborately produced collector series — they were working emergency money, and survivors tend to show it.
