There is currently a Game of Thrones-themed art show at the Dernier Bar Avant la Fin du Monde (the Last Bar before the End of the World) in Paris. At the link, you can see many of the works available. My favorite is this heroic scene of Tyrion Lannister by Ronan Toulhoat. The victorious and bloodied unsung hero of the Battle of the Blackwater is clearly cast in the image of Frank Frazetta's The Death Dealer.
