† Gibbons  differentiates between two stamps of the same design with the SG-A1 overprinted on SG356 (printed in Wellington from Royle plates) and the SG-A2 on SG352c (printed in Wellington from Waterlow plates).
Both entities are areas of Antartica. The 1908 Shackleton expedition took stamps with them, intending to stop at King Edward VII but, due to bad weather, went to Victoria Land instead. The ill-fated 1911 Scott expedition took the Victoria Land inscribed stamps.
Scott  lists both issues within the normal run of New Zealand stamps. Gibbons has a separate listing between NZ and the Dependencies headed "Antarctic Expeditions".
