Another Curly Question

I have a figurine of a bird - photos attached - which has a felted bottom - my question is - would you remove the felt to look for an indication of who the maker is?

 

I'm run to an end of possibilities.

 

it is handbuilt from a heavy bodied, earthenware clay...14.5cms tall.

 

and it's just the ugliest little bird sculpture I've ever seen..
