George Rodrique
Based on a familiar Cajun folk tale, the loup-garou is a mythical werewolf that roams around places at night. Rodrigue remembers being told as a child to go to bed or else the loup-garou would get him. A boogie man story. The legend bore him this painting, set in a full moon landscape, which gave the dog the blue tint, and subsequently, gave the world an iconic image.
