These thumbnails refer to commercial artwork, all believed to be by Roy Carnon, used for book covers. If you know more please tell me. Originally published by "Four Square" or "Corgi Books" Many of the books may be available for sale on web sites such as Amazon and eBay. Some may be available as free download ebooks or html web pages. If you interested in buying one of these books, and have a specific interest in the picture on the cover, then check you are getting the right version. Many of these books were published with alternative cover designs. I am also interested in any "motor show" related art by Roy Carnon.
