Have you heard of a painting artist called/named "Kam"?

I have a painting of a man in a green tank top type dress on a horse, no saddle, with another horse next to him. Both horses are white. There is no background, only red/burgundy. It's signed "Kam". Has anyone ever heard of this artist or own a painting by him/her? The painting was given to my father and we'd love to know who the artist is.
