Lance Richbourg is a well-respected sports artist. You can see some of his stuff here: http://www.superstock.co.uk/search/Richbourg

His father (also named Lance Richbourg) was an outfielder for the Boston Braves in the 20's and 30's. He attended the University of Florida and was the first Gator to play professional sports. Lance Jr. also attended UF and I believe is now an art professor at a college in Vermont.
