About a month ago, illustrator Robert Ullman sent his latest promo postcard — featuring Bill O'Reilly and Keith Olbermann Al Franken (thanks Aaron!) as Rock'Em Sock'Em Robots — to a bunch of art directors, including "five or six contacts at Entertainment Weekly".

Imagine his surprise to open the latest copy of EW and see an illustration of Bill O'Reilly and Keith Olbermann as Rock'Em Sock'Em Robots rendered by another illustrator. Coincidence? Maybe. Link
