Bill Sienkiewicz is an American artist whose arrival at Marvel Comics in the early 1980s redefined what was possible within mainstream superhero art. Beginning as a Neal Adams protégé on Moon Knight, he evolved rapidly toward a radical mixed-media style — combining photo-collage, expressionist brushwork and graphic design — that produced landmark works including Elektra: Assassin (with Frank Miller) and his own Stray Toasters. An Eisner Hall of Fame inductee, Sienkiewicz remains one of the medium’s most formally adventurous image-makers.
