Portuguese Macao Don Carlos I Bisect Surcharge 5a on 10a
Macao · 1911 · 5 avos on 10 avos
This stamp features a bisected surcharge of 5 avos on a 10 avos stamp, originally depicting King Don Carlos I. It is further overprinted with 'REPUBLICA', signifying the transition from monarchy to republic in Portugal and its colonies.
Issued in the wake of the 1910 Portuguese revolution, these stamps were created by overprinting existing colonial issues with 'REPUBLICA' and often bisecting them to create new denominations due to stamp shortages in Macao.
