Spanish Morocco 1920 10c on 10c Carmine Rose, Surcharge Inverted

Spanish Morocco · 1920 · 10c on 10c

This stamp is a definitive issue from Spanish Morocco, created by surcharging an existing Spanish stamp. It features a 10 centimos surcharge on a 10 centimos carmine rose stamp, but this particular variety is notable for having the surcharge printed upside down, creating a collectible error.

In 1920, Spanish Morocco was a protectorate of Spain. Surcharging existing Spanish stamps was a common and economical way to create valid postage for use within the protectorate's territory.
