German note, not found listed

Hello there,

I have this german note, which should be some kind of internment/prison note from Metz prisoner of war camp.

I may be blind but I can't find it in the catalog. Any help? 🥺

It's not in the catalog yet, you will have to add it. Probably Paper exonumia → Internment and prison vouchers → Germany (LINK)

Also exists in 20 Pfennig denomination (LINK).
