I did a bit of research and found the following page:
http://www.owenartstudios.com/bio_beacham_owen.html
Here it says:
"His work has been seen in AutoWeek, Cycle World, Motorcyclist, Racer, Road & Track, Roadracing World and Sport Rider magazines. He also appeared twice on Late-Night with David Letterman.
In 1996, Beacham was commissioned by Miller Brewing Company's South Pacific distributor to paint Bobby Rahal in his MGD champ car to celebrate his finish in the Australian race. The artist has since painted the top racers in Formula One, CART, Moto GP, World Superbike and the Isle of Man TT. He also paints vintage street scenes and modern sport-touring motorcycle scenes that are very popular."
So ... call it as you will ... but he basically finds pictures on the internet, blows them up ... re-does them as digital art or air brush, copies them like mad and sells them on the inter-weeb. Because of his credibility, he can't be pulled from eBay for copyright infringement.
