Group 013 B - Notgeld collage C1918 - 1920s.

A brief explanation appears in the note to my album on Notgeld, but here it is just for you, I also note that, along with the art work, the quality of both paper and printing varies considerably, the largest of these notes is around 100mm x 75mm (give or take a couple of mm), the smallest being about 45 x 30 mm:
Titled as 'Group **A or B' showing both sides of respective notes. this is a series of collages of a collection of notgeld; the German name covers monetary items that may be issued by an institution in times of economic or political crisis. The issue is usually made with no official central government sanction, usually arises when sufficient state-produced money is not available and generally refers to money produced in Germany and Austria during World War I.
I may not of attributed the correct names here and there, but tried my best!

The representation of seemingly historic events on some of the notes would, I think, be interesting to research for more detailed information.
