This striking airmail set, issued in 1966, commemorates the 3rd anniversary of the Congolese Revolution. The designs draw parallels between Congo’s revolutionary spirit and other historic uprisings: the 25 Francs shows President Alphonse Massamba-Débat and the Presidential Palace in Brazzaville, the 30 Francs features Robespierre with the storming of the Bastille, and the 50 Francs depicts Lenin alongside the Winter Palace in St. Petersburg. Printed by Delrieu and designed by Monvoisin, these stamps symbolize international revolutionary solidarity, making the set a key thematic issue for collectors of African independence and political history.
