Papua 1906 2s6d black and brown, SG28Papua 1906 (8 Nov) 2s6d black and brown, type 3 large 'Papua' overprint of Port Moresby, thin paper, WATERMARK VERTICAL, SG28. A brilliant unmounted mint upper right corner marginal example with full original gum. The stamp has a trivial surface speck but is quite exceptional as it is unmounted mint example of this key British Empire rarity featuring the Lakatoi (trading canoe) with Hanuabada Village in the background. Surely the finest extant example
