This work, an abstracted study of an animal head, shows Pousette-Dart's interest in tribal and Jungian themes of confrontation and sacrifice. These themes are the main focus of his work in the 1930s and early 40s. The oval shape is repeated and modified to suggest eye, horn, egg, yolk, and fetus, all surrounded by his characteristic black contour line.
Inspired by a true story, Invincible recounts the last 48 hours in the life of Marc-Antoine Bernier, a 14-year-old boy on a desperate quest for freedom.
