1908 German 100 Mark “Reichsbanknote’ (Emergency Bank Note)

“Notgeld (German for “emergency money” or “nescessity money”) refers to money issued by an institution in a time of economic or political crisis. This occurs usually when sufficient state-produced money is not available from the central bank. Most notably, notgeld generally refers to money produced in Germany and Austria during World War 1 and the Interbellum.”
