Someone is showing around her house, pointing at some printings of paintings on a wall by a famous painter. She says:
I wanted an original of hers but she never has them available.
Christmasy time home decoration
"...she never has them available." caught my attention.
At first, I thought that it might mean the painter paints but never sell them, so she never puts them on sale.
Then I thought it might also mean, she paints them, puts them on sale, they are all sold, but she doesn't paint any new paintings, so no paintings has been available for a very long time.
I think the first one makes more sense, but what about second one?
