Portugal Ceres 100 Reis Blue, Inverted Center

Portugal · 1912 · 100 Reis

This stamp is part of the first definitive series of the Portuguese Republic, featuring an allegorical depiction of Ceres, the Roman goddess of agriculture. This particular example is a famous error variety where the central vignette of Ceres is printed upside down in relation to the frame.

Issued shortly after the 1910 revolution that established the Portuguese First Republic, the Ceres series replaced stamps bearing the image of the deposed monarchy, symbolizing the new republican values.
