Here is a rather nice 50 Pfennig banknote issued as a credit note by the District of Diepholz in 1921.
It has wonderfully historic art work with Lemförde as a town in 1621 and on the other side two knights in armour with a variety of local crests based on the Lemförd and Diepholz crests. The lion on the crests is taken from the original arms of the Count of Diepholz.
Lemförde itself is near Lake Dümmer which is about 15 kilometers from Diepholz itself. This lake is surrounded by fens that support many rare bird species and is a favorite spot for ornithologists from around the world.
A great opportunity to get a notgeld banknote that is not so common.
