Modernist Slab-built Porcelain Vase - signed but ???

I picked this up several years ago but I've never found anything similar. It is clearly signed but I can't read it - ?? Joel Kleafer ??. None of the combinations I've tried come up with anything.

It is 10" high and has a matte finish. The black is incorporated into the porcelain which is quite translucent.

Does anybody recognize it?

 

Josef Klaferz???? The Josef is right, unless it's just Jose. Someone who is better at deciphering bad handwriting ought to come along soon.

 

so Mr. Anderson, how the mod on the 20th Century forum gets the 1st name as Lucy..... is beyond me ...

Genz baby who can't read script, and who used Google Lens!? It says Josef over there too. Josef Klein-something?

 

I doubt this will help but I put little dots to fill in between some of the almost there lines. If you told me it was Josie Klu Lerz I'd probably believe you but I have no idea what it says.
