Zanzibar #16b, 1895 3r green and brown Victoria with inverted "r" in "Zanzibar" overprint, attractive and well centered with full Zanzibar cds cancel dated 10.JA.96. There are a few shorter perfs at top which are mentioned for accuracy only and which are not mentioned in the accompanying 1995 Royal Philatelic Society of London certificate ("used is genuine"). This is one of the rarest major errors of Zanzibar, with only a few examples recorded, and even rarer in used condition (we do not recall seeing another used example). A lovely showpiece for the serious British Africa collector (SG 20k £4,750 = $9,500). Scott CV $5250
