Featured Need help with identification with these cool glass vases

Hey folks!

Bought these lovely white glass vases with interesting mark underneath them but can’t figure out the maker. Google search gave me some Danish tulip vase maker Anker Iversen, but I don’t think they have marks as these ones have.
Marks look like some kind of animal or bird, but again, not sure.

Any ideas?


Thanks a lot!

Is that a mark or just broken pontil?

 

it’s not broken as they both have the same thing and no sharp edges. It is definitely some sort of mark or signature.

 

I'll bet its a simulated pontil mark....
