Issued in October 1944, this banknote represents the early post-Liberation currency of France following the Nazi occupation. The selection of René Descartes—the 17th-century French philosopher and mathematician—reflects the nation's cultural pride and intellectual heritage during the period of national reconstruction. The allegorical angel figure on the reverse symbolizes France's liberation and renewed hope, embodying the spirit of the Fourth Republic's founding principles during this pivotal moment in French history.
The obverse features a three-quarter portrait of René Descartes positioned on the right side, depicted with long dark hair, pale complexion, and wearing a burgundy-brown 17th-century coat with white collar—authentic to the philosopher's historical period. Behind Descartes sits an allegorical female figure in classical dress representing France or learning, positioned against a seascape or harbor landscape. The reverse displays a monumental winged female allegorical figure (Liberty or France) in classical Greco-Roman style, semi-nude with exposed breast, holding a large shield or badge, positioned before an expansive cityscape with fortifications, buildings, and crowds of people, suggesting liberation and national renewal. Both sides feature ornamental vine and leaf motifs framing the design, with decorative scroll elements in the corners. The color scheme employs sage green, blue-gray, cream, brown, and gold tones characteristic of French engraving work of this period.
