Paul Windle has done editorial illustrations about economic disparity, elections, New York cultural landmarks and our relationship with Abraham Lincoln. But credits in Bloomberg, Businessweek and the New York Times don't mean he can't sketch up a Stegosaurus wielding a sword while riding a skateboard or revel in the facial hair of baseball players from the mid- to late-1970s.

Windle's Flickr stream is especially fun to look over. He clearly has a particular affection for sports: the people who play it, the people who write about and, of course, the fans. Plus, all those 1970s ballplayers' faces make for a neat pattern—check it out on the background of his Twitter page. And his "Prehistoric Gnar" series is just ridiculous, unpretentious fun.
