Janko Domsic left Croatia and arrived in France in the 1930s. He reportedly received an elementary education, spent time in prison, lived in Toul, and worked on railway construction. In Paris, he lived in poverty, occupying a small hallway in a modest building near Place de Clichy.

His drawings, created with colored pencil, ballpoint pen, and felt-tip pen, combine geometric figures and texts, mixing French, Croatian, and German, which list fragments of his life in reference to mystical ideas, the moral code of Freemasonry, and economics. Powerful graphic symbols—the pentagram, the swastika, the dollar sign, the communist hammer and sickle, the Orthodox cross—and rays from the sky structure a work deliberately coded by its creator.
