50 Francs

The BCEAO was established in 1959 as the successor to the Institut d'Émission de l'Afrique Occidentale Française et du Togo, created to manage the CFA franc across the newly independent former French West African territories. This note, Pick 1 for the issuer, was transitional in the most literal sense — the bank existed before the member states had fully separated, and the undated issues were used across multiple countries simultaneously, which is why so many different signature combinations appear on a single type. Each pairing reflects a different signatory from a different member state's administration rather than successive periods of issue.

Robert Julienne's consistent presence across every signature variant is worth noting — he held a fixed position within the central structure while the countersigning authority rotated by territory.
