Help to decipher signature on glass bud vase

Please would you cast your eyes over this signature?
The vase is around 7” tall and I can’t work out what it says!
Found in the UK if that helps.
Cleaning is work in progress as it was black with filth inside and out!
Thank you for looking

 

Yolanda J... ?

 

Could be. Thanks for looking

 

It's a lovely vase, but I can't make heads nor tails of that/those signatures! Here's something inverted to ponder though!!! The bottom one has some strange faint-ish lettering in the middle also....might want to try tagging @anundverkaufen .....he's often VERY good at signatures!!!

Ooh, well spotted. I’ll go and have another look in the centre.
Great work with inverting it, certainly makes it clearer, Thankyou.

 

Kosta Lindestrand are similar with the spiral and slightly overturned rim but that’s not what that signature says.
Edit- I’ve just had a look and even with a magnifier that stamp in the centre is so faint that Aqui’s image is the only think to go on. I would never have even realised that was there! It’s not visible to the naked eye.

 

Hm. I've seen that design, it's certainly Scandi.

 

That’s a starting point. Bugs me when I can’t ID something!

 

It looks reminiscent of 1950s work by Vicke Lindstrand, but the signature does appear different.
