Depicts the coat of arms of São Tomé and Príncipe, encircled by the colony's name in Portuguese at the top, and the date positioned below.

The coats of arms of the Portuguese colonies were introduced in 1935. All arms were of the same model: divided vertically in such a way that two sub-shields are formed. The dexter was white with five small blue shields each bearing five white discs (i.e. Cinco Quinas, Five Quinas representing the motherland). The sinister represented the colony. The colonial sub-shields for São Tomé and Príncipe depicted a mill-wheel with drops of water flying off. This was the personal symbol of king Alphonso V (1438-81), during whose reign the islands were discovered. In the base green and white waves to indicate the overseas location. To complete the badge, the arms were set upon a golden armillary sphere with a golden mural crown. The crown had 5 apparent towers in each tower charged an armillary sphere and in each space between towers charged Christ’s cross.
