Henriette Valium (aka Patrick Henley), is a comic book artist and painter living in Montreal. Valium gained some recognition in the underground comic scene in Europe and North America in the 1980s, but his outrageous style has kept him on the margins of the comic book industry.

Valium is for sure one of the greatest cartoonist of all time. For the last three decades his creations have been widely dispersed in numerous underground anthologies, fanzines, self-published oversized silkscreen comics, and various mixed-media collaborations. He’s become a regular in almost every independent zine, compilation and catalogue in North America and Europe. The heavy black lines and manic detailing of Valium’s psychotic storylines demand attention, weeding out any casual readers.

In his extremely peculiar way, Valium explores the rotting decay of an urban environment that he obsessively renders and depicts in horrific, sometimes nonsensical way. He’s hilariously fascinated as well with every possible corruptions of the human body and it’s mind: sickness, addictions, abnormal sexuality and social decay, exposing our culture’s fears and hypocrisies with an acute, caustic, sharp and absurd sense of humor. Many say that his books are more about creating an experience than reading a comic book. I say there’s nothing wrong about being both.
