A classic postage due stamp from Cameroon, issued under French administration, featuring the traditional Chiffre-Taxe numeral design. The bold red 10 centimes value sits within an intricate geometric spiral background, a hallmark of French colonial due issues. Marked “RF” (République Française), this stamp was used to collect unpaid or insufficient postage from recipients. Typography and engraving were produced by the Institut de Gravure, giving it sharp lines and strong visual appeal. A must-have for collectors of French colonies, postage dues, and early African postal history.
