vintage Ugly Scary Spooky Old lady Halloween Face pottery MUG cup - $50 (W. Salem)

TO be honest, I'm not really sure what I have.
What I know is my Aunt gave this to me shortly after I graduated high school in 1988.
I never used it.
I don't drink coffee.
It has sat in my memories box up in the attic for 30+ years.
It is hand made, old, has a stamp of "AP" on the bottom.
Stands 6" tall and 3" wide w/ a huge handle.
It's heavy.
Like I said, I've never used it.
It is used but new condition.
