A side-effect is that there is little biographical information available on the Internet regarding Tomaso. His Wikipedia entry relies heavily on a tiny entry in one of Walt Reed's books on illustrators. It mentions that Tomaso was a teacher as well as an active illustrator, and that he also did fine art painting.
Therefore, all I can do for now is present for your evaluation some images of his that I could find on the Internet.
