Inflation had never been a topic of a museum exhibition. With the outbreak of World War I the gold standard was given up. In Germany the war was financed by war bonds and by printing money. Already by 1919, the mark had lost 90 % of its value. Despite the galloping inflation until 1922 there was full employment. But finally in November 1923 the mark went under. The currency reform made a 1 billion paper Mark equal to 1 new Rentenmark. The exhibition tries to generate an easily interpretable graphic image of this financial and economic process.
