Is my picture, of Queen Alexandra, drawn by C.W. Walton and signed 'Alexandra' worth anything?

I know for sure that C.W. Walton was a passed governor-general of Canada, turn of the century,but don't think he was a famous painter.

You must mean 'titled Alexandra'. Can you post a picture of your artwork. Is it oil, watercolor, acrylic. If it was of Alexandra it would have been oil on canvas.

C.W. (Charles William) Walton, draughtsman, lithographer and publisher, lived and worked during the late 1800s.
The National Gallery in London, England, has several works by C.W. Walton in their collection.
I have an artist's proof by this artist. It is a drawing of King Haakon of Norway. I am in the process of trying to have it valued, but have no idea of its worth.
