"Cover" was a rather prolific artist on eBay at one time, though he seems to have eased off lately. I'm not sure if he has his own "style"
or (as his name suggests) he covers other peoples styles of art. Some pieces are obviously based on artists such as Bruce Timm and Amanda Conner, others are a bit harder to place.
Whatever. The art is of a good quality and a pleasure to view, and it probably makes a pleasant change from the daily grind of Architectural Illustration.
If anyone can give me some more info on the artist please do contact me.
