Do you recognize this teapot?

Tidying up the kitchen today we found a teapot which is somewhat familiar. And so we say, do you recognize this teapot?
It does not belong in our kitchen and underneath it says "this item is ornamental only and not to be used as a teapot". So we ask also, what should it be used for?

Ernest again.

It is not that we are stalking Ernest, but....
Yesterday She tidied Her studio, with a bit of help from us. She is still painting like a donkey, so thought that a clear out might help and we found this, by Tsugouharu Leonard Foujita, a Japanese painter working in France. Must have had a past life as an artist's model.

We found

a picture of Ernest on a bottle of beer.
