Unmarked Brutalist Copper Pitcher: Any Ideas?

Hello!

Here is a recent thrift store purchase of mine. It is approximately 30 cm tall and weighs 611 grams. I think it is lovely, although I was surprised it had no markings on it whatsoever. Perhaps that means its exact origin / age cannot be identified, but I thought there is a chance that perhaps someone here might recognize it, so why not try posting it

Any help would be appreciated!

 

Looks like a tree trunk
