Portrait on TV sitcom Will & Grace?

On the (now off air) NBC sitcom Will & Grace, there was a collection of paintings that were hung around Will’s apartment. They were portraits of a man who had a striking resemblance to Will. All I know about them, is that the art director for the show looked around for male themed art & found these & had copies made for the show. Does anyone know who the artist is & where (if possible) I can buy either the originals or copies of these paintings? Thank you for any help you can provide, for I have been trying to find these since episode 1 aired back in 1998.
