Hey Daniel,
What you have is called Note Geld, or emergancy money issued by the city of Bielefeld. Nearly every city and village issued this type of note (note means "paper money", Note means "emergancy"). This note is interesting with the two Regiments represented, and I would expect them to have been raised in the area of Bielefeld.
Best wishes
Gus
I forgot to mention that this was the beginning of the runaway inflation of the post war period.
