Having demonstrated very little in the way of artistic talent (in my lifetime) and having zero technical training, I find this an astonishing revelation. To look at Rebour's work (which is impressive enough), and realize that he did it from photographs that he took at trade shows, just moves him up a notch. He was, obviously, pretty damn good with a camera (particularly considering the photographic equipment in those days)? Thanks for that keen piece of information, Chuck.
