Help to ID, probably WGP (Jopeko?)

I found on a local flea market this vase without any identification signs. The seller told me that it was made in Germany. Could you tell me who made it, have you seen it before?
Height: 18 cm, maximum diameter: 13 cm.






I searched all the web for similar designs, but all I could find is this Jopeko vase.
Jopeko Mid Century black & white fat lava bud vase with red rings encircling the vase.
Height: 15 CM / 6 Inches

If the red one has a sticker or is marked in some way, yes; otherwise, you're back where you started.
