100 Francs

The BCEAO was established in 1959 as the successor institution to the Institut d'Émission de l'Afrique Occidentale Française, created specifically to serve the newly independent francophone West African states while keeping them anchored to the CFA franc zone. Robert Julienne's consistent presence across every signature combination here reflects his role as the French-appointed Director General — a fixed counterweight to the rotating national representatives, each drawn from a different member state.

The "K" suffix in the Pick reference designates Senegal as the country of issue within the common series. Six distinct signature pairings across four years on a single 100-franc type is unusually dense for this denomination.
