Hey,

It's German notgeld from the city of Altona.

A different dated one is on Numista over here:
https://en.numista.com/catalogue/note224523.html

On colnect you see also the ones from your date:

There appear to be some different version with the watermark, I can't see by your pictures which one you have :)

Sala.

Thankyou very much.
Very interesting, I didn't know about that. Mine is the first type.
Bye bye
