Hamburg Zoo Ticket? Or What Is It?

Thanks Medieval. I was not familiar with the term "notgeld" and did not find it in our glossary. Wikipedia defines it thus: Notgeld (German for "emergency money" or "necessity money") refers to money issued by an institution in a time of economic or political crisis. The issuing institution is usually one without official sanction from the central government. 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 I and the Interbellum. Issuing institutions could be a town's savings banks, municipality and private or state-owned firms.

Serienscheine notgeld issued by the Zoological Gardens in Hamburg. These were not really "emergency money" as the value of the mark was such that the pfennig denominated notes were near worthless. Serienscheine were more like souvenirs to be sold to collectors in sets (series).
