Blue ceramic bears by Muriel?

Hi
Can anyone identify the origin of these ceramic bears?
I think it says Muriel (although we did debate Mumel) in the signatures.
But I can't find anything quite like them online.
They were part of an auction lot of polar bear ornaments many of which were from the USA or Canada - but some were UK.



Thank you for any help you can offer.

Lovely :) There’s a Muriel Harris in the U.K. who made animal figurines but these look more Canadian in style

They are really sweet. The polar bear collection was a surprise - most of the lot was Denby! - and I am trying to work out what to keep, what to carboot and what to try to auction named and labelled better.

Thank you Naomi. I can't find any pictures of her things online. But they do feel 'different'. They are matt, and lovely to hold. And they seem quite robust (some small people were playing with them yesterday!)
