Identify leather bowl

My cousin bought this at an auction in Southern Illinois. She assumes it is Native American, but some have suggested African origin. There are some pictures (not great quality I’m afraid) here:

It is about 24 inches across at the top. The bottom is partially collapsed.

Any information will be greatly appreciated.

Interesting, never seen anything quite like it.

I think it’s Dr. Filth’s. He keeps his world inside it, but all his sexless patients keep trying to blow it up.

Looks like I should have come up with a sexier title!
Assuming anyone is still interested, I probably should have described it as rawhide, rather than leather.

I think it’s one of the first attempts at a meat hat. It looks like this one was supposed to be a bowler.

I can honestly say I’ve never seen anything African like that.

I keep getting malware warnings on that link, from totally unrelated computers.
