This commemorative stamp from Portugal, issued for Madeira in 1980, reproduces the classic 1868 20 Reis King Luís I issue, one of the earliest Portuguese colonial stamps. The design features the traditional profile silhouette within an ornate frame, with the bold overprint "MADEIRA" signifying its use in the archipelago. Issued at a face value of 6.50 escudos, it marked the period 1868–1980, celebrating over a century of Madeiran postal history. Collectors prize this issue both for its nostalgic homage to early Portuguese philately and its significance in regional postal autonomy.
