Artist Jack Vettriano might not get respect from critics, but his work gets a big vote of priase on the auction floor. “An auction of 40 paintings by Jack Vettriano, a self-taught artist snubbed by national collections, has raised £2.5m at Sotheby’s in Scotland. The highest sum paid was £330,400 for Mad Dogs – painted in 1991 when he was selling work for a few hundred pounds.”
