The Portuguese issued stamps for their many colonies in Africa plus Macao, Azores, Maderia & Portuguese India. In all, depending on what is included there are around 25 different colonies and areas you could collect the stamps and / or postal history of. As great travellers these areas had often been under Portuguese control or influence from the 14th or 15th Century but the first stamps created for overseas territories were those Portuguese stamps overprinted for Azores & Maderia in 1868, then the unique designs for Portuguese India first issued in 1871, and the most utilized first issue ‘Crown’ types appeared in the early 1870s.
These wonderful stamps are copiously overprinted and surcharged around the turn of the 19th Century, earlier issues with differing levels of complexity offer shades, perforation changes and much else, later we see the emergence of beautiful pictorial stamps perhaps the most famous being the Nyassa Company 1901 Animals set with inverted centres! A simply fabulous philatelic area to collect there is arguably nothing better than a comprehensive stamp album of Portuguese Colonial stamps and covers. We recommend the excellent stamp listings in the Stanley Gibbons or Afinsa catalogues.
