Vintage Germany Pottery Vase by Zeller Keramik. It is black with hand painted colorful flowers. It still has the original stickers on the bottom. One says:
Zeller – Keramik
Kuntzgewerge – Geschenke
Seifert – Singler
7615 Zell Am Harmersbach
The other sticker says: V 403 / 20
I think it may have been made by the same company that makes the Cock and Hens dishes.
No chips on rim. There are a few little spots missing black paint to the right of the front flower scene. They are quite tiny and not that noticeable. Looking down into the inside it appears to have a coiled bottom.
