Help Identifying and valueing a Libby Anderson painting

I have a very large framed painting of a woman standing in front of a piano and violin. It is signed Libby any info would help.

Peter, if you haven’t already, you can contact Libby directly by clicking the “Email Me” link up at the top of her gallery page:

Hi! I am Libby Anderson,
That is not one of my paintings; haven’t ever done musical instruments in my paintings- agood idea though. It must be another Libby.
