Not Sure How To Describe This Pottery Vase Abstract? Trying To Figure Out By Who?

Cool little vase that I've had packed away for some years just wondered if someone might recognize who made it by the style or the unreadable mark on the bottom

 

Someone on here suggested sprinkling a little flour or cornstarch on the bottom over those letters to see if they stand out any better......worth a try......DRY...NOT wet!!!!

 

It sort of looks like numbers on the bottom to me, 538177? Is there more writing below that? It sort of looks like a German bottom to me.

Looks sort of Mondrian style.

(how is that for a lot of non-committing?)

 

Did the flour trick and it does look like numbers

 

Probably Bay Keramik.

 

Agreed, anund.

 

I found a very similar shape listed as a Jasba Keramik vase, bit its active so i wont post the link
