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.

Much of Valium’s work is self-published; it can take him up to six years to produce one comic book. He creates his own outlandish characters and stories and illustrates them with paintings that often take months to complete. L’Association, a highly-regarded French publisher of comic books, is working on a complete anthology of Valium’s comics.
